I agree completely with removing the belly pan as part of the oil change.
Only 6 screws hold it on, and they are easily removed with a drill driver and socket.
I just got done doing the oil change on my 2022 Massimo 550F (Linhai 493, w/oversize dropside steel bed),
All of the grief I endured with oil splurt, oil filter drainage and dropped parts & tools made me regret not removing that pan.
Besides, at this point you also have the opportunity to clean the dirt, mud and stones that have accumulated in the area under the engine.
