You didn't need to, they are the defaults and have been so since Samba

Nothing there about SMBv1.
I would raise the log level to at least 5 and see if something 'pops'
out during normal use, other than that, I would be looking closely at
Apache, could it be trying to use SMBv1 ?

It's Nginx not Apache, and it's not web-related anyway: The delay occurs
when I simply double-click on the Samba host in Windows' Network section 
to see its shares. FWIW, I didn't have that problem with Debian 11; I 
had to install a fresh Debian 12 from scratch after the USB thumb drive 
from which it ran failed :-/
