Changing Azure Function APP root certificate

I have a wifi device WINC3400, that uses HTTP GET to access my Azure Function APP. In the last few days, we have not been able to connect to the API from the devices.

After some investigation, It seems the issue is related to the root certificate on the Azure Function App

Previously it was BaltimoreCyberTrustRoot, but now it's DigiCertGlobalRootG2.

My device does not have DigiCertGlobalRootG2 yet. Therefore it is not able to connect to the API.

Would it be possible to go back to the BaltimoreCyberTrustRoot, till I can get my device to update the root cert?
