Hi All,
Standalone - DSS:
UE is not sending ratematchinglte-crs IE.
Does that mean DSS not supported by UE?

Yes.

rateMatchingLTE-CRS
Indicates whether the UE supports receiving PDSCH with resource mapping that excludes the REs determined by the higher layer configuration LTE-carrier configuring common RS, as specified in TS 38.214 [12].

ETSI TS 138 306
5G; NR; User Equipment (UE) radio access capabilities
(3GPP TS 38.306 version 15.5.0 Release 15)

I would guess that UE not supporting DSS should not camp on SA-DSS cell. DSS capability is in SIB 1
