Anyway to change the Blanking Lines on Bazzite like you do in CRU on Windows?

Ive already kinda tried to ask for help on Reddit for this, and seemed to only get a possible lead that kinda went nowhere. Im only using Windows right now, bcuz increasing the Blanking Lines in CRU solved the issue i had with my 7900xtx. Where the VRAM would spike to 909MHz and sit idly there, while my board power went up to 56w. Increasing the blanking lines helped bring the VRAM clock down and my board power now sits at 12w-20w on idle. I tried to see if i can do this in Bazzite but I have only seen people mention how to change the custom resolution using xandr, with no mention of the blanking lines or customizing the freesync range. I want to stop using Windows as I am just tired of shit not working like they are supposed to. Please and thank yous. Im also a Linux noob so please bear with me, as I dont understand all the terms and lingos yet.
