I tried this way Dinh, but it doesn't work in dts, compile gives error.
 /delete-node/ cpu@2;
 /delete-node/ cpu@3;
works correctly.

Anyway I will send v2 patch with a socfpga_agilex3.dtsi for Agilex3 
silicon which include "socfpga_agilex5.dtsi" and delete the cpu2 and 
cpu3 in dtsi file instead of dts.

Thanks,
