First Flight Test PID tuning

Hi dears
I bought all what I need for my first flight (very exited to do it ).
I wondering how to tune my PID’s before to switch to Auto mode ?
If i flight manual is the plane tune PID and return them to log file in MP ?(I don’t think so )
Please is there any way to be sure of my parameters before switch to auto mode ?
Thanks in Advance and sorry I am beginner in this .
