i have both Python 2.7.17 and Python 3.6.9 on my Xubuntu 18.04 LTS based laptop without using pyenv. i just don't code for Python 2. But i did need to run some old scripts on Python 2 to have a reference. i believe Python 3 was intended to coexist with Python 2, at least until the EOL date, 1 Jan 2020. i see no reason for it to have been changed since then.
if you have any Python 2 scripts that other tools run or other people use, don't use pyenv for Python 2. likewise, if you will be rewriting them to Python 3 (as you should have long ago) don't use pyenv for Python 3, either.
it sounds like you have a lot to upgrade, there.
