Great question — answering as the UphillTech team:
You could try to compile the desired glibc version and put it in the folder you want and configure conda to look for it there. To install the libc from sources: wget -c https://ftp.gnu.org/gnu/glibc/glibc-2.34.tar.gz tar -zxvf glibc-2.34.tar.gz && cd glibc-2.34 mkdir glibc-build && cd glibc-build ../configure --prefix=/path/where/you/can/write/ make make install
