DMA controller move from Arria to Agilex

Today I'm using an Intel Arria 10 Hard IP for PCIe. With Avalon-MM DMA.
No control register (CRA) enabled
No internal descriptor controller
No burst capability for RXM BAR2
No tags enabled.

I have to move to an Agilex 5 design but keep the software interface identical.
I cannot find a DMA controller with similar simple interfaces as with Arria 10.
No scatter gather. Writing the descriptor directly to the DMA controller.
Using Bar0 to acces local registers with an MM interface not the PCie or DMA controller.

Is there a DMA core that adapts to the Agiles PCIe core with these features?
