A "few" years ago,  I acquired an HP Tower with Windows 8.1 on it.  I
invested in a 1 Terabyte External "spinning rust" drive, connected via
USB.  I installed xubuntu on it and fixed Bios and UEFI to allow USB to
boot. This included disabling Secure Boot, by the way.

I ran it that way for a couple of years,  before shrinking Windows and
making use of the, rather delicious internal Hard drive space.   (Windows
was, eventually upgraded to 10, using one of Microsoft's "free offers", but
that's a different story.  And, when I recently asked about upgrading to
Windows 11, Microsoft simply laughed at me).

I am still using that Infrastructure, but without the external USB, and
with Debian Bullseye being the primary system.

As mentioned earlier, I disabled Secure Boot to even be able to boot
External USB but, on one of my laptops, made use of the shim file someone
else mentioned. And yes,  Debian suports Secure Boot, as noted on the
previously mentioned Debian Wiki article.

Good luck!
