Hard vibration when sitting at stop light in Drive (2.5L 2020 Camry)

So I have a 2020 Camry LE with the 2.5L engine and I've noticed over the past 1-2 months, the car has developed what I would call a vibration when the car is sitting at a stoplight in drive. The vibration goes away (mostly) if I put the car into neutral and is not noticeable when I take my foot off the brake. It doesn't stall or anything, and accellerates normally.

At first I thought maybe I had bought some bad gas but it's been about 4 full tanks now and I ran some injector cleaner through but no change.

I will say that temperature perhaps plays a very small role as I notice the vibration less when it's a bit warmer (say 45 degrees or warmer) and it's more noticeable when its colder out. Doesn't matter if the tank is full or near empty, does the same thing. Car drives and shifts fine otherwise, so I don't know that it's necessarily a transmission problem. It's 3 years old now with about 35k on it so it's still under the powertrain warranty.

I did notice there is apparently a recall on some from 2020 that may have bad fuel pumps, and that made me wonder if perhaps this is an early sign of possible pump issues (it doesn't have any issues starting in the morning -- warm or cold days). All fluids look fine.

It's going in for an oil change in about 3 weeks so I may just talk to the dealer then about it, but wanted to know if there is anything else I should maybe check just to be sure. It's not related to tires or suspension either (had that checked already). I do notice the car periodically will make what i call a putting sound but it doesn't seem to impact the actual idle of the car (and the idle seems normal and is steady, about 650 rpm when warmed up).

The only other thing I can think of would be a bad/broken motor mount somewhere but my guess is that if it's broken it would likely make more noise or vibrate more or all the time (while driving and at idle). However I wonder if it's possible if a cracked motor mount might be the issue?? (The car has not experienced any hard impacts that would cause a motor mount to break necessarily, so if it does turn out to be one, it's likely defective). But again, at startup I don't notice this while it's fast-idling to warm up. Only once it's warmed up.

(And as a side note, the catalytic converter is still there -- this was checked, although we did not check to see if perhaps there is an issue with the exhaust though. This was done when the car was on a lift checking other stuff.) Also no check engine light or warning lights, so whatever it is, it's must not be that significant to trip any codes.

Any suggestions on things to check?

I have a code reader so maybe I'll start there. No lights though, so wondering if it's possible for it to throw codes without tripping the check engine light or any messages on the dash display.

One thing I'm starting to wonder is if it's maybe an exhaust issue, hence the slight putting sound I'm hearing, or some internal issue with the exhaust valves perhaps. It does make this "ringing" sound periodically when idling say at a stpolight, but it's always done this from day one. But some have told me that it shouldn't make any noise of that type (the noise only lasts maybe 5 seconds and then stops, but it seems this sound has become more frequent (one person told me it was a self-cleaning system but others have said that this isn't true). Just something else I thought I'd throw in there.

"one person told me it was a self-cleaning system"
May be referring to the fuel injection system being direct plus intake injected.
Reason being is the intake injection helps keep the valves free of carbon deposits.

The two systems are used at different times so you may be hearing/feeling a change as they are switch on/off.
