Fixed Height Hover (Alt Hold) Pixhawk 2.4.8

Hi guys, I would like to ask if you happen to know if theres a chance where I can set a height limit to hover like example for 3 meters only. Then it will just hover on that height and even though Im pushing the throttle up it wont go any further? Have you guys done this? Thanks

Not gonna happen. You add throttle > Motor RPMs go up. Motor RPMs go up > Props make more thrust. Props make more thrust > Aircraft climbs.

The proper way is to establish a hover and switch to AltHold.
