Hi Andrew,
The Anafi thermal has a FLIR thermal-imaging camera with a resolution of 160X120 which is not enough for thermal mapping with Pix4Dmapper (It should be at least 640X480).
Processing Thermal Images
Same issue with the Mavic 2 Entreprise Dual:
DJI-Mavic-2-Enterprise-Dual
A new version of Pix4Dcapture iOS (4.5.0) is now available on the store that supports the Parrot Anafi Thermal (Only RGB images):
https://itunes.apple.com/us/app/pix4dcapture/id953486050
However it does not support thermal images and it is not planned in a near future.
Sorry about that.
Best
