How to fake non-priviledged user in docker container?

I have to call two commands, the first one is turning on vpn which needs root, the other one is rpmbuild which don't want to work on root due to security vulnerabilities. I want to cheat and fake non-root user to call rpmbuild. I don't think i would run into security troubles running it under docker in CI, so i want to neglect that

I cannot do

USER user  
...  
USER root

because all commands run during runtime and in the single script, so i had to manage both paths for default user directories like /home/user and /root

To run a specific command in the script as non-root user, you can use the command su - user -c "<command>". After the command specified in -c argument is executed, it will go back to run the next commands as root user to turn on the VPN

su - user -c "rpmbuild ..." # Run rmpbuild as non-root user
# Turning on VPN as root below
...
