Volume groups on a VPS doesn’t make much sense, in my opinion and experience.
You can install from Distro ISO and not get volume groups if you boot with the parameter nolvm added to the kernel command line.
The resulting partition scheme is 95% of the disk formatted ext4 for the root partition and 5% for swap.
Alternatively, if your disk is already partitioned and formatted and ready to go, you can boot with skip-hdd-setup and the ISO will just start installing to it.
