convert from BIOS to UEFI

I'm considering converting from BIOS to UEFI to make my boot faster.
Will it be faster?
Am I going to run into UEFI bugs?

I read I need to convert my partition table from MBR to GPT first.

gdisk gave me this warning.
>Warning! Secondary partition table overlaps the last partition by
33 blocks!

Looks fine to me:

Device Start End
/dev/nvme0n1p2                262146047
/dev/nvme0n1p3      262146048
What is the problem?

$ sudo gdisk /dev/nvme0n1
GPT fdisk (gdisk) version 1.0.3

Partition table scan:
  MBR: MBR only
  BSD: not present
  APM: not present
  GPT: not present


***************************************************************
Found invalid GPT and valid MBR; converting MBR to GPT format
in memory. THIS OPERATION IS POTENTIALLY DESTRUCTIVE! Exit by
typing 'q' if you don't want to convert your MBR partitions
to GPT format!

You will need to delete this partition or resize it in another utility.

Command (? for help): q

$ sudo fdisk /dev/nvme0n1

Welcome to fdisk (util-linux 2.33.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
