-Silent payment capable PSBTs can be uniquely identified the same way as PSBTv2s, except when including silent payment outputs. If an output contains the the PSBT_OUT_SP_V0_INFO field, it must use that field instead of PSBT_OUT_SCRIPT as the output script when creating the unsigned transaction used for unique identification.<ref name="why_use_sp_info_field"> ''' Why use PSBT_OUT_SP_V0_INFO when serializing for a unique identifier?''' Since the same silent payment capable PSBT is valid whether or not a PSBT_OUT_SCRIPT is included in an output that has PSBT_OUT_SP_V0_INFO set, using the PSBT_OUT_SCRIPT if present for the unique identifier will cause malleability. The identifier will be different depending on whether PSBT_OUT_SCRIPT is present, so always using PSBT_OUT_SP_V0_INFO if it exists makes sure the PSBT is always identified uniquely.</ref>

 The PSBT_OUT_SP_V0_INFO should be serialized as a zero byte for the version, followed by the 33 bytes of the scan key and then 33 bytes for the spend key.
