You cannot add PS Ethernet AXI Manager to a custom board in the FPGA Board Manager because only supported boards have pre-configured PS Ethernet interfaces. For custom boards, only JTAG AXI Manager is available.
For MATLAB's "loadBitstream" function, if your board is not listed, you need to create a custom board definition using the FPGA Board Manager in MATLAB. Add your board details there, and then you can use loadBitstream with your custom board. For more information on this, refer to the following MathWorks documentation:

I hope this is beneficial!
