Install texlive following the instructions at the tug site.
This will put  texlive 2025 in /usr/local/texlive/2025  but will not affect
your existing tex in any way
Do not change your default PATH, in a shell where you want to use tl2025 do

export PATH=/usr/local/texlive/2025/bin/x86_64-linux:$PATH

and all tex related programs will pick up the upstream tex and set their
input paths accordingly (as they are set relative to the location of the
binary)
