Bybit maintenance margin

On Bybit I went long and placed two limit sells to go from long to short which increased my margin from 50x to 80x, making the position more vulnerable to liquidation. On another occasion the first limit sell filled and I added a second one at ask price that did not fill.

Is there a way to go from long to short and vice versa without increasing margin or having to add an additional limit order after the first is filled?

I guess I could add/remove the second limit order as the price approaches it, but still leaves the position exposed.
