S/MIME encryption keys in Exchange profile for iOS
Currently Apple requires that the private keys are provided by the MDM system and must be included in the Exchange profile. Please add support for existing S/MIME private keys by an upload API function for the PFX files.
SCEP/PKCS profile is no option, because this would only generate new keys and not use the already existing keys of the user.
I have confirmation from the program manager that this feature is in development. It should release in the next few months.

looks like it worked but is disabled ATM, look here:
Any ETA to make this available again?
I don’t really get why it’s not there in the new portal.
Intune Hybrid and the old Portal let me configure Import policies for S/mime.
As I need the same private key on all my devices imported it doesn’t make any sense to enroll a new certificate used for decryption.
