I don't think it will make much sense that x2 interface is missing. Can you elaborate more on your question so that complete picture of the query is clear.

X2 is an optional interface. Is it up to operator to enable/disable this interface. Due to X2 interface, Handover for an UE can be done faster than the S1-based .

eNodeBs can also share information to each other using the X2 interface.
For more details, please go through 3GPP 36.423.
If you still have any doubt or query, please ask .

Consider Two ENB of two different operator can they establish X2-AP Connection if X2-AP Support is there ???

I guess it is possible as ECGI will give unique identification to them . (Though possibility of CGI is same) ...

is there any other scenario like x2AP- is not possible between them

In case of hub-and-spoke topology, X2 messaging can travel all the way back to an aggregation point, which may be co-located with EPC. In such scenario both X2 and S1 traverses same physical path (a.k.a X2 over S1). Please consider both Intra-MME and Inter-MME handover scenarios. Would X2 based handover in such a case yield advantage over S1 based handover. Thanks.
