How can I set my OpenGL renderer to LLVM?

A specific application requires me to be using LLVM (LLVMPipe?) as OpenGL renderer (glxinfo | grep renderer). I've read that it's the default renderer if none other is found, but I don't want to go uninstalling drivers just to change this if possible. This is my current output:

glxinfo | grep renderer
OpenGL renderer string: NVIDIA GeForce RTX 3070/PCIe/SSE

In case this is some sort of XY problem, the program I'm trying to run is TASlib with software rendering

As the SE thread points out: nvidia will ignore that.

You could try to run the program in xephyr.

Edit

__GLX_VENDOR_LIBRARY_NAME=mesa glxinfo -B

Replacing glxinfo w/ your program will work likewise.
