I would like to know if after installing android on the nintendo switch it is possible to reverse the process, that is to have the original nintendo switch operating system again. Can be done???

You install android on sd card not on Switch memory
So you have 2 separate systems.
If you want go back to Switch original os just reboot Switch.
