idle surging while in Drive

I'm an old, retired guy with a recently purchased 2021 SR5 4wd, 6cyl access cab Tacoma with 21K miles, I live in Minnesota.

I have a very tight spot to park in and at idle creeping into my spot the I get an unpredictable Un commanded idle increase of about 5 to 7 rpm making parking a challenge.

Truck operates normal, no fault lights and operates normal while driving.
The rise in RPM is proceeded by a solenoid click that I'm guessing is the Idle Air Control Valve and the command to that solenoid I'm guessing comes from the Engine Control Unit which maybe senses a low idle. I don't think I can raise the idle with an adjustment.
Anyone have ideas of what the problem could be or how to trouble shoot.
The dealership told me without a fault light their must not be a problem. ha ha
