Delete Windows 10 on an M.2 SSD?

I would like to completely clean the SSD from my laptop so that it is put back on FreeDos. How do I do that? Unfortunately I didn't find anything on Google.

Hi

for freedos you need a floppy drive, do you have one in the laptop?

here is a compendium of the installation

practically have to start from floppy and delete all partitions with fdisk

and create and format a freedos partition (fat)
