You can use the gparted tool to graphically remove the partition(s) and then format them to whatever file system type you are interested in and just have those mounted as extra data drives. Or merge them into your Linux partition (depending on setup). That will require gparted to be run as sudo as you are interacting with disks.

Alternatively, you can a tool like fdisk to change partitioning in terminal. You can pull the disk info using something like lsblk, so if you had a specific drive it might be sudo fdisk /dev/nvme0n1, then you'd want to print the current table and look through the help.
