The "big" man tool uses /etc/man_db.conf to override these.

I committed a change which allows that to work:

    man: allow nroff and tbl commands be overridden; unmangle writing to files

    Parse this in config files:
         DEFINE col ...
         DEFINE tbl ...
         DEFINE nroff ...
    Add width options to nroff command line.
    Use "tbl", not "gtbl", as default tbl command.
    Export GROFF_NO_SGR=1 and use "col -b -p -x" instead of pager when
writing to file.

Please try current git, try making it work for you with suitable
/etc/man_db.conf,
let me know if it's not sufficient.
