installed driver as DKMS, but changing paramiters in sys doesn't persist after reboot

[SuperDuperDragon64]

hello, recently i performed a fresh install and wanted to get this driver working again. on my old OS I installed it via the make command before discovering that it needed to be reinstalled after every kernel update, and so following a guide someone posted on here I installed the driver with the DKMS command and was able to use it just fine until my fresh install.

by creating a DKMS at the start I thought i would save myself a lot of trouble whenever i wanted to use my tablet, but as i keep mine upside down the orientation needs to be flipped for it to work properly. changing the setting in sys via nano as root seems to work but it doesn't persist after a reboot. is there something specific i need to do? I'm kind of new to the more advanced sides of Linux and while i read something about a terminal based config program i can't figure out how to access it.
