If you install Proxmox VE the next time and are not happy with the default layout, check out the parameters for LVM [0]. I personally prefer to install on ZFS as all ZFS datasets share the same free space unlike with LVM.

If you want full control of the disk layout and maybe want to do some more custom stuff, consider installing a base Debian and then install Proxmox VE on top of it [1].

The PVE installer makes it easy to get a system up and running quickly but is opinionated what the disk layout should be. That of course might not be working for everyone.
