P1S quite mode start up

New owner of a P1S here. I have an A1 and an A1- mini, I have been able to remark out the start up gcode to stop the vibration routine. I am wondering if anyone knows how to and if I can do that with my P1S?

Hello, look in the link, there is a suggested solution, I tried it and it works, it does not cause any damage, but the support of BBL points out that such changes could lead to restrictions of the warranty
