Looks like the defaults are hardcoded to el7:

  - 'https://github.com/NVIDIA/enroot/releases/download/v{{ enroot_version }}/enroot-{{ enroot_version_string }}.el7.x86_64.rpm'
  - 'https://github.com/NVIDIA/enroot/releases/download/v{{ enroot_version }}/enroot+caps-{{ enroot_version_string }}.el7.x86_64.rpm'

Host is running Centos 8.5:
