I would very much expect it to, but I too would advise checking it
after you have finished using gparted.

I would also expect you to create some partitions as well. At this
point, things aren't so clear. I've read that gparted my change the
protective MBR to a hybrid¹ one under some circumstances. However,
I don't know what those circumstances are.

Neither can I find matches for "protective" or "hybrid" in the manual.²

I would recommend using gdisk. There's a cgdisk variant that uses
curses if you need a display, rather than typing p occasionally.
You could hardly do better than start reading at:
https://www.rodsbooks.com/gdisk/
which has more resources at the end of that page. (Some of the links
duplicate the documentation contained in the gdisk package itself.)
