I just finished the Lego 42095 Stunt Racer and noticed that there is a slight drift to the right when it drives forward. It works fine in reverse mode - reverses in a straight line.

Any suggestions, solutions please?

The best way to do this is that the motors are running at a slightly different RPM If both left and right motors run at exactly the same RPM they make us a straight line. PF L motors don't have rotation sensors to drive in straigth by default.
