I drive a lot of retro cars and can say that while there usually wasn’t a dedicated mode you could turn down or off all of the interior lights. For example my 2001 Jeep Cherokee it’s just turning the light knob (same applies for the '91) as for my 2001 Toyota Tacoma it’s a matter of turning the dedicated knob that’s funnily enough the same spot as the one on the Cherokee.
