I would expect to see some vibration whilst sitting on ground, not good to sit too long like that though these have been known to tip over trying to correct against a puff of wind or uneven ground.
A calibration won't do any harm though, and at least eliminates that when tracking down problems.
Do all props look intact, no chips or debris that might cause additional vibration ?
The calibrations I would do from scratch would be:-
1) Sensors (Using DJI Assistant 2 v1.2.2, or latest version), usually done just after update on Assistant 2.
2) IMU (level surface).
Using the newer '3D' IMU calibration routine, my last two IMU calibrations have been done at about 20C ambient air temperature. The subsequent IMU warm up time when aircraft is first powered up and initialising does not seem to have been adversely affected, and warm up time is a few seconds at most.
3) Gimbal (just after IMU).
4) RC sticks (with aircraft off).
5) And compass (in an open area (not over steel reinforced concrete), away from ferrous materials or electromagnetic interference). Get one good calibration, and that should be all that is needed until informed by system or erratic flying that needs investigation. Note that any ferrous metals very close to legs (steel frame in desk, cutlery in kitchen drawer, windowsill strengthening etc) will generate a 'compass error', this does not mean compass needs recalibration, just move the aircraft away from source of interference.
