Awesome thank you.
The thing is that i've configured my build to be exclusively a 1 device system only.
Basically i don't really need any extra boot options because technically i should have just 1 and nothing more.
All of my system and files are on 1 m.2 SSD from now on, the system is super tidy and clean this way and quite light, if not considering the PSU. i also disabled all of the other SATA ports on the motherboard via the BIOS.
Later on if i decide to upgrade to a larger SSD ill just reinstall the OS.
The issue for me was that macOS really really liked being on just one drive, for example software like Logic Pro X will NOT install
on a drive other than the main OS drive, and even while i can make a symbolic link and try to force it and install it else where
all of the libraries still require the home folder, and using symbolic links for them is just extremely buggy, software loads very slow and sometimes gives an error.
