Sounds like the fuel injectors on a cold start up.

Yes it sounds normal but different from previous model years before 2017 and back. I too feel this sound is unusual and my car does it too.

Is this normal?

Been having this sound every time I turn on my Camry is it normal? Should I be concerned? It goes away after a few minutes
Perfectly normal and OK. The 8th generation Camry and 5th gen RAV4 use the same 2.5 liter Dynamic Force engine. It has BOTH port and direct fuel injectors (8 total). What you hear on start up --the clattering noise--are the direct injectors. After a brief period that noise goes away when the port injectors operate. The 2 sets of injectors cycle on and off when the engine runs. There is also a high pressure fuel pump for the direct injectors mounted on the engine which contributes to the noise.

My 21 SE 4 cylinder does the same. Everyone says fuel octane doesn't do anything but I swear putting 93 in mine quiets it down. Just my 2 cents, hope this helps!
