Hi, Can anyone suggest few ARM socs that supports, PCIe 4.0/3.0, NVMe 4.0/3.0/2.0?

Most of them will require signing NDA papers, but you can look around mediatek, rockchip, Allwinner or qualcomm as typical arm SoC vendors, or try your luck around fpga's like xillinx zynq (I do not recommend them because of their policies), altera/Intel or lattice
