One random guy (who only posted twice in 10 years) on page 1 claimed that it was disabled, which means diddly. HP, Canon and Epson continue to sell multi-function printers with fax capabilities in 2024. Microsoft only sells Windows 11 in 2024. Therefore you can fax within Windows 11 somehow.
We know that Microsoft fixed a security vulnerability in Windows 11 Fax services in March 2022.

Microsoft moved stuff around and documentation lagged. So the Microsoft staff (on page 1) gave the old way to get the windows Fax and Scan app. The current way was posted on page 3.
There is a thread here (I can't find it at the moment) that talks about not able to get the print to fax option in the new printer dialog, which was fixed by (I can't remember how) activating the old classic printer dialog. But that was a problem for large corporate environment.
Edit: Found the thread, if you don't get the print to fax option in your printer dialog, then you have to enable legacy printer dialog.
