Separations grayed out in print window

[klseiz]

I am trying to print color separations and haven't had a problem until now. The selection isn't available anymore! I'm not sure what to do now.

Running MacBook Pro 13 inch 2020 with OS 11.6

Try to change the Printer to Adobe PostScript File

It's still grayed out. Ugh.

And if you then change the  Mode from Composite to Separations (Host-Based)?

Yeah, I've found out it is a Big Sur OS situation. I don't have print upgrades for any of my printers that are only a couple of years old (and they are already going to Monterey?!?) So I had to downgrade one of my computers back to Catalina to be able to get the full print driver capabilities.
