Hi. I found that the rpcbind(8) man-page explains a reason for that behavior.
It is included in Bionic, not Focal.
ubu1804:$ man rpcbind
(snip)
-r Turn on remote calls. Cause rpcbind to open up random listening
ports. Note that rpcinfo need this feature turned on for work
properly.
(snip)
Ubuntu note: to retain backwards compatibility with existing behavior,
in releases Xenial and Bionic, the default for this is enabled,
so remote calls are turned on by default.
(snip)
In Focal and later, the remote calls default is disabled, and
the variable is ignored.
ubu2004:$ man rpcbind

FILES
If "/etc/default/rpcbind" exists, rpcbind will use the specified options
at launch time rpcbind Otherwise rpcbind will try to load configuration
from "/etc/rppcbind.conf" rpcbind The default options are set as "-w -f".
So, I edit /etc/default/rpcbind and restart rpcbind.
ubu2004:$ diff -u /etc/default/rpcbind.orig /etc/default/rpcbind

It seems to be working properly.
