"No."
That was quoting Simon Urbanek from a few years ago. You cannot undo what it
is in R's own /etc/R/Makeconf via a programmatic way via some sort of option
or alike. It is fixed. You and I know that you can add to the right-hand side
via ~/.R/Makeconf and that is about it AFAIK.
Of course you can also call `sed` and alike to modify it (in a container,
say). Maybe that is what you really want to do.
Actually, it is also a 'conffile' as far as `apt` and friends are
concerned.
So you can always do `sudo vi ...` it and call it a day. The changes should
persist in the way changes you the admin made to your config files persist.
I am afraid that is all we have here.
