Yes under 230.85(2) or 230.85(3) when the correct listed equipment is used.
In my area cold sequence meter disconnects are not permitted for dwellings, so 230.85(2) can't be applied.
Equipment that is SUSE rated can be used for 230.85(3), but Meter-Main equipment is listed Suitable Only for Use as Service Equipment and can only be used for 230.85(1) applications IMO.
Yes, if you have a meter main, that is the service disconnect. If you don't want the service disconnect outside, you install the new meter can and a suitable disconnect switch as the required emergency disconnect, and leave the bonding and grounding at the location of the panel that contains the service disconnect.
