It's documented to work [1], but you need to remove these single
quotes. For instance:

$ env PGOPTIONS="-c os.user=$USER" psql -d postgres
psql (12.4 (Debian 12.4-1.pgdg90+1))
Type "help" for help.

postgres=> show "os.user";
 os.user
---------
 daniel
(1 row)

If characters needed to be quoted in the value, backslash
should be used as the quote character. Since it's also
a quote character for the shell, two levels of quoting
are needed:

$ env PGOPTIONS="-c os.user=user\\ is\\ $USER" psql -d postgres
psql (12.4 (Debian 12.4-1.pgdg90+1))
Type "help" for help.

postgres=> show "os.user";
    os.user
----------------
 user is daniel
(1 row)
