From Dual boot to Single boot windows

Hi there, i just found my old Hi12 tablet again. Android is outdated and I was wondering if there is a way to setup the device to just act like a normal windows laptop running windows 11. So getting rid of the dual boot bios and such and just run a single OS. Saving the disk space for windows only.

I am too want to do that
I tried install win 11 on boot. the install doesnt find any drives…

There is a YT video where the guy installs Windows 11 on Chuwi Hi12 tablet.
