Just to share this question and answers with other community users.
In Tridion Sites 9.0 DXA 2.0 with Model Service implementation, we had an option to control not to remove the extension and strip-index-path for the component link resolver in the model service.
It was done by applying the following flags in the dxa.properties:
Now, We have upgraded to Tridion Sites 9.5 with DXA 2.2 and used the DXA model extension, and deployed via add-on service.
DXA Model Extention deployed in Content Service and works as PCA APIs.
My question is How and Where is this config managed for this setup?
