Switching RST to AHCI without losing data (feddit.de)

My laptop switched from AHCI to RST on its own (probably after a Windows update) and now I cannot boot my Kubuntu anymore. Live sticks also cannot access the drives. When I try to switch it back in the UEFI settings, it tells me that it will wipe the drive to do so.

Is this message correct? How can I change it back without losing all my data?

The device in question is a Lenovo Ideapad 720-15ikb with Kubuntu and Win10 dual boot.

My acer laptop did the exact same thing for unknown reasons. When I switched it back to AHCI Arch (btw) booted again but windows broke and I managed to fix it with a Windows live usb. I think I had to use bcdboot and generate a new bootloader.
