No, it is actually unusual, even with Cat-less DPs, to get DTCs on the VR30.

Based on what I see, you should check to make sure the electrical connections to the primary O2 sensor on Bank 2 (driver's side) are seated properly and are not damaged.

P2098 Infiniti Post Catalyst Fuel Trim System Too Lean Bank 2

Possible causes
– Faulty Heated Oxygen Sensor
– Heated Oxygen Sensor harness is open or shorted
– Heated Oxygen Sensor circuit poor electrical connection
– Exhaust leaks
– Contaminated Heated Oxygen Sensor

Put another way, if it was the Cat-less DPs that ware the issue, then you would get DTCs on Bank 1 and Bank 2, but Bank 1 appears to functioning normally, even with the Cat-less DP.
