If one wants to install using LVM (for comfortable file systems resizing) with XFS /, there are 2 options (both very uncomfortable) :
after installation create a new logical volume, format it as XFS, copy content (using tar for example), adapt /etc/fstab and if needed grub configuration.
Install using Ubuntu server and then install ubuntu-mate-core package.
A simple solution can be to replace disk partition utility within installation media/ISO with the one used by Ubuntu Server media/ISO.
Correct me if I’m wrong but I thought these were added as options when installing the interim release Ubuntu MATE 25.04 “Plucky Puffin”. At least I remember LVM was an option when I checked it out.
