Can you go via a temporary file instead, i.e. output what you want to
grab to a temporary file and pull the info from that instead?

I'm a proponent of customizing the library path via .Renviron instead
of via .Rprofile. In your case, you can have a line in ~/.Renviron
with:
R_USER_LIBS=~/R/%p-library/%v-bioc_3.12
Alternatively, you can set it elsewhere, e.g. ~/.bashrc, in a Linux
environment module that is loaded, and so on.
BTW, using Rscript --no-init-file ... would skip .Rprofile while still
parsing .Renviron.
