(voxl-suite: 1.4.5) 
Hi, I recently bought a Starling 2 Max drone, and I was following the [developer bootcamp](https://docs.modalai.com/voxl-developer-bootcamp/) to get the drone running indoors. 
While following the First Flight Tutorial, I noticed that the drone didn't have a valid position estimate. I traced this to the fact that the voxl-qvio-server was |Disabled| and |Not Running|. 

To fix this, I used the "voxl-configure-mpa" command. While this fixed the original issue, and now voxl-qvio-server is |Enabled| and |Running|, I've got a missing /data/px4/param/parameters_baro_tc.cal file, and no idea how to calibrate it.

My output for $ voxl-check-calibration
Calibration File Status:
Present /data/modalai/voxl-imu-server.cal 
Present /data/modalai/opencv_tracking_front_intrinsics.yml 
Present /data/modalai/opencv_tracking_down_intrinsics.yml 
Present /data/px4/param/parameters_gyro.cal 
Present /data/px4/param/parameters_acc.cal 
Present /data/px4/param/parameters_level.cal 
Missing /data/px4/param/parameters_baro_tc.cal 
Present /data/px4/param/parameters_mag.cal 

Detected Missing Calibration Files
please run the required cals
https://docs.modalai.com/calibration/

Although the drone runs well in Position control mode, even with the missing cal file, I am worried if this affect the position estimate of the drone.

I tried, following [Documentation](https://docs.modalai.com/calibration/), but am unsure if there is a way to configure just this sensor, as I don't really want to mess with the working conf files. Also, is there a way to get the default/factory conf files back? 

Thank you for your help!
