Flashing the F5121 firmware could work (at least with custom roms it only has no dual-sim support so it could be enough to backup the keys).

The drm-keys unlock some functionality on android but won't be needed at all on Sailfish OS or custom android roms (there are drm-fixed-kernels available for custom roms which restore those features).

In many places (eu afaik so you'll be fine until brexit is done ) they aren't even needed to "restore" warranty since wiping the warranty by unlocking your bootloader is not allowed there.

So unless you're going to sell the phone or you plan on ever running stock rom on it again you don't need to backup your drm-keys (can't hurt though).
