I don't think there's anything like that supported in a general way.
I've seen 3GPP scan implementations return e.g. the RAT in addition to
network name/MCCMNC (e.g. in QMI NAS Network Scan), but not really the
signal quality % or RSSI.

That said, in QMI there is the "QMI NAS Get Cell Location Info", that
may give you what you're looking for, and probably other protocols for
other modems also have something similar. What kind of modem are you
using?

Nah, there's nothing we can do about that. The modems return the whole
list all together once the scan has been finished.

Nope, modems don't give us an interface like that one.

Nope, again, modems return the whole list all together once the scan
has been finished :/

The newer QMI services, though, work in a total async way, where you
request something and you get the results asynchronously via
indications (that would align with what you're looking for), but I
haven't analyzed them thoroughly to be able to say that there are QMI
commands that would let you run an scan in that way.
