Hi guys, welcome to Ask MHS!.
In this tutorial I'll provide a tutorial or tips anout How To Mount EFI Partition Quickly in Mac (OS X or macOS). So this is the best way to mount your EFI Partition couse you don't need any 3rd-party apps to do it. So, how to do it?

1. First thing you need is Terminal, so please open your Terminal apps.
2. The next is you have to know you disk identifier in order to know in which partition or disk the EFI is located (this is needed to know if you have more than one disk in your Mac device), but if you have just on disk in your Mac it means your EFI is located in /dev/disk0s1

You can run diskutil list to know the disk identifier.

3. Mount your EFI partition by running this command
diskutil mount /dev/disk0s1

Note : Change disk0s1 with your EFI partition identifier.

Additional  :

Run diskutil umount /dev/disk_identifier to unmount your EFI partition.
