I have Big Sur installed in a VMware Fusion Player virtual machine. I desire to disable SIP. With an actual physical Mac, the usual method would involve first booting to internal macOS Recovery, then entering the command given below in a Terminal window.
However, booting to internal macOS Recovery does not seem possible. The holding down the ⌘+R key combination at startup does not work. The Mac Startup Manager does not appear to exist. I can restart to firmware, but the
Recovery volume does not have a
boot.efi which can be chosen to boot from.
I realize the SIP setting is stored in the 4 byte NVRAM variable given below.
The firmware does allow booting to a built‑in EFI 1.0 shell. However, this shell does not appear to have any commands which can modify this variable. In fact, the variable does not even currently exist in the virtual machine NVRAM. I tried entering the command below in a macOS Terminal window.
sudo nvram csr-active-config=%7f%00%00%00
The result was the error message given below.
nvram: Error setting variable - 'csr-active-config': (iokit/common) not permitted
What procedures can be used used to disable SIP?
I am using the current free version of VMware Fusion Player (Version 12.1.0).

Below are a links to sites with procedures that either I could not get to work or only work with previous versions of macOS.
