modem manager starts too early

Dear MM community,

I have an issue with MM startup.
It seems that it starts communicating with the modem in the middle of
the USB enumeration.
My modem, ALAS5, has 4 cdc-acm ports and 1 cdc-mbim interface
(including a /dev/cdc-wdmX port).
Sometimes MM starts sending AT commands when only 2 ports are detected.
It is a question of miiliseconds, maybe just of the cpu schedule.
Ofono sets a guardtime of 1 second from the time the first device of
the USB enumeration is detected.
Would it be possible to have a similar mechanism in MM?  Or is there
already something?

Thank you,
Kind Regards,
Giacinto
