How to Install Ubuntu Server on a Specific Disk (e.g., /dev/sdm) with LVM?

Hi,

I want to install Ubuntu Server on a machine with multiple disks. Previously, the installer automatically placed the OS on /dev/sda, but I need it installed on /dev/sdm instead, using an LVM layout.

How can I manually select the target disk during installation to ensure the OS is installed on /dev/sdm? Are there specific steps in the Ubuntu Server installer to enforce this?

Thanks for your help!
