Few hacks:
There is a way to set up alerts on mobile app that will alert you as margin drops dangerously. It only works on mobile app
Buying near the money PUTs might improve margin situation in emergency. One needs to have Above 10% of mrg cushion left to buy anything.
Margin requirement for covered PUT (100 sh + PUT) is, as I see it in Canada, 10% of PUT value + 100% of how much SP is above PUT strike.
2022 was quite scary experience, so far. I have realized that instead of engaging in selling PUTs, which I see now as poor strategy, I should have been PUTs buyer.

You need to do the math for your situation but buying PUTs ~400 might be better than liquidation order with limit 310.
Those PUTs were very cheap when SP was at ATH
