Fix Bios Boot partition

[PVTD]

Hi, I think I just made a mistake while trying to expand the available drive space.
So, I recently cloned my PVE boot drive (sdd) from a 64gb to a 512gb SSD and wanted to recover the unused space via lvresize but it would give me an error that it already is at max cap, yet it still shows 59Gb total space.
I then used lsblk -f and noticed sdd1 had nothing:

sdd                                                                                            
├─sdd1                                                                                          
├─sdd2                  vfat   FAT32       5B06-047C                               510.7M     0% /boot/efi
└─sdd3                  LVM2_m LVM2        S3s05v-iWf6-a3ag-vLjv-7x7Z-mvz0-1ldGfY              
  ├─pve-swap            swap   1           7c765844-6186-440a-94e7-02444190ffc0                  [SWAP]
  └─pve-root            ext4   1.0         fcee1934-f9a8-4495-bd2e-5fedc144d14e     17.7G    58% /

My idiotic brain thought, oh there is the missing space so I ended up mkfs -t ext4 /dev/sdd1 as per suggestion on another thread.
Then in the "Disk" menu on PVE the empty row changed to BIOS boot. Uh oh...

sdd

├─sdd2                        vfat        FAT32          5B06-047C                               510.7M     0% /boot/efi

  ├─pve-swap                  swap        1              7c765844-6186-440a-94e7-02444190ffc0                  [SWAP]

Now, I haven't restarted the server yet with the idea that I could still fix it while not losing any long downtimes (if this forms an issue). My gameservers run on it and I play with friends and we had some plans this week.

I'm a great hardware guy, linux has not been the easiest for me to learn (various reasons) but I do try to get better at it. Don't shoot me plz I already feel like an idiot...
