How come I have so many entries in efibootmgr?

I run EOS/Cinnamon on a Thinkpad T14 Gen 1, using systemd-boot & dracut. efibootmgr shows me lots of entries, I wonder where these come from and if some cleanup would be required:

$ efibootmgr

Aren’t those from OEM’s implemetation of UEFI?

My Lenovo ThinkPad 1 has a lot of entries that they added, but are not used. Seems to be their standard.

Cheers for the feedback!

Seems no need to worry, and Lenovo pre-implementing a lot of menu and fallback options there.
