Description of problem:

Listing the variables using "efivar -l", on VMWare systems, there seem to be no Mok* variable available or visible:
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
# efivar -l | egrep "(Mok|Sbat)"
#
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------

The variables are only present in /sys/firmware/efi/mok-variables directory:
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
# ls -l /sys/firmware/efi/mok-variables/
total 0
-r--------. 1 root root   0 Mar 10 01:42 MokIgnoreDB
-r--------. 1 root root 964 Mar 10 01:42 MokListRT
-r--------. 1 root root  76 Mar 10 01:42 MokListXRT
-r--------. 1 root root   0 Mar 10 01:42 MokSBStateRT
-r--------. 1 root root  18 Mar 10 01:42 SbatLevelRT
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------

Trying to understand why this happens, while booting in Verbose mode, I can see a difference between my KVM system and VMWare system:

- KVM

Here above on line "mok.c:855" on VMWare there is a **Success** instead of **Invalid Parameter** on KVM.
I don't know if it's relevant or not.

Version-Release number of selected component (if applicable):

shim-x64-15.4-2.el8_1.x86_64


How reproducible:

Always

Steps to Reproduce:
1. Boot a VMWare VM in UEFI mode

Actual results:

No variables

Expected results:
