How to slow down the adjustment in precision LAND mode?

I used the companion computer’s precision landing on the UAV, but I found that the UAV adjusted so much that it lost its target once it adjusted (attitude <= 2m), you know what I mean.What parameters should I tune?Or where to adjust the PID parameter used in Percision Land mode?Thank you for your help!
