Lightroom Classic: Suppression des défauts - Paramètres personalisés.

Google Translate:
For LrC, LR and Camera Raw, to date, it is not possible to save the map of points set for the elimination of faults. I do not know if it is relevant for sensor spots, but for a set of photos taken with the same apn, the sensor defects will always be present in the same place of the sensor until we have cleaned the sensor of the 'apn.
The options menu used to define which functions are saved in the custom parameter does not have the Fault removal tools option! So we can't save it!

Considering sensor spots can change when you change lenses, turn the camera on/off if you have auto dust removal turned on, use large or small aperatures, or just normal use throughout the day a friend of mine uses a method that has worked well.  He takes one photo of the sky or another blank area at the start of the day or whenever he feels there might be a major change.  He will correct the spots for theses photos making sure to NOT manually move the source spot as that locks the source.  He then uses this dummy file  to copy/paste the sensor spot removal to the other photos. I do nature photos (macro, landscape, critters) most of the time and only do spot removal on the keepers so don't use this method much.
