Hello.

How do I tell mac OS Big Sur v11.6.4 to never sleep when using in a 2020 Intel MBP? I only want to set this as a test since I'm trying to figure
out why this MBP crashes when waking up after sleeping once in a while.
So far on power AC connection, it never crashes with sleep disabled.
macOS Big Sur v11.6.(3&4) doesn't have an option to do that. I only can disable its power nap and display sleep.

Thank you for reading and hopefully answering soon. :)

There should be an option in System Preferences > Energy Saver called
"Prevent your Mac from automatically sleeping when the display is off". Enabling that option will cause the computer to stay awake even when the display sleeps.

If you want the display to never sleep, set the "Turn display off after" setting to "Never". If you do that, it's probably best to make sure you
have a screen saver enabled too.

Otherwise, as the saying goes, "There's an app for that". I've used
Amphetamine for years to prevent sleep when certain apps or processes
are running, and it's a nice tool to have handy for such a thing:
