Is it possible to tell mpv to act like subtitles don't exist

I am practicing Japanese, and as a practice tool, I sometimes want to watch anime without subtitles. I know I can turn off subtitles in mpv using hotkeys, and I am also aware of --sid=0; however, in both these situations, I am one hotkey away from re-enabling the subtitles. This is bad because I often find myself tempted to re-enable the subs way too often, which seriously hinders language learning. So I was wondering if there is some way to tell mpv that the subtitles within a file don't exist, so that, even if I really wanted to see the subtitles, I'd have to completely restart mpv.
