Pixracer-PX4-QGC avionics power low warning

Recently picked up official pixracer kit and installed it in a quad. Was surprised how quickly I got it in the air. Couple of small issues I noticed (9 years of quad building). The biggest one at the moment for me is the continued “avionics power low” warning. A couple of posts here and there have indicated it isn’t true and there is a voltage divider problem on the board. Is there a fix for this?
