Any way to "unload" a controlnet model from memory when Controlnet is disabled?

Description
I know I'm really pushing it with a 1660TI 6GB on a laptop but, I've noticed if I use a difference control and then use a different one I get CUDA OOM errors and I have to restart the webUI completely to use another. So my guess is they just hang around in memory even if you don't have Controlnet enabled.
I don't know if this is the right place to ask this question/suggestion.

Research direction
Start by tracing how ControlNet models are loaded and retained when switching controls or disabling ControlNet, then reproduce the CUDA out-of-memory error on a 6GB GPU. Done means switching to a different control or disabling ControlNet releases enough model memory to avoid restarting the web UI.
