Is there a way to set the SOCK_DIR on macOS

[tintack]

The SOCK_DIR is default to the temp dir on macOS.
The value is from the env var TMPDIR, and in my case, it's a folder in /far/folders/...

I have a project using nix, and it sets the TMPDIR env var to a different value.
So the sessions I create outside of the nix-shell is unavailable in the nix-shell.

Is there a way to set the SOCK_DIR to a fixed place?
