S9+ custom rom install without buttons

I want to install android 14 one ui 6.1 onto my Samsung Galaxy S9+ but the problem is, all my buttons literally are gone, no volume, bixby, or power button, I use a pin to start it and now even that's almost impossible to do since I guess I wore out the inside part of the power button thingy, that aside, the phone's running android 10 with root, so is there anyway I can go through all the steps of installing a custom rom without buttons? Any help would really be appreciated :D
