This can easily be done after the fact. I'm using this for quite a
while now and it works like a charm. See also

Thanks for suggesting the use of Lmod "hide-version" for hiding
unwanted/obsolete/system modules from the "module avail" command! There
are also some useful hints in
https://github.com/TACC/Lmod/blob/master/Transition_to_Lmod7.txt.
IMHO, this is the best available solution in stead of rebuilding your
entire module tree from scratch (which may still be what we want to do
in the long term).
I've written the attached script for conveniently generating a
~/.modulerc file from a list of module name patterns which you want to
hide. On a CentOS 7 system with the Lmod RPM from EPEL, you can copy
the .modulerc file to the Lmod system default file /usr/share/lmod/etc/rc.
For the record, I've also documented this procedure and the script in my
EasyBuild Wiki page at
https://wiki.fysik.dtu.dk/niflheim/EasyBuild_modules#hiding-modules-with-lmod
