I found the solution and it works:

set subnet-parameters "class "pxeclient"{match if substring(option vendor-class-identifier, 0, 9) = "PXEClient";"
set subnet-parameters "       if substring (option vendor-class-identifier,15,5)="00000" {  "
set subnet-parameters "      #BIOS client   "
set subnet-parameters "     filename "boot\\x86\\wdsnbp.com";   "
set subnet-parameters  "      }  " 
set subnet-parameters  "      elsif substring (option vendor-class-identifier, 15,5)="00006" {  "
set subnet-parameters   "     #EFI client 32bit  "
set subnet-parameters   "    filename "boot\\x86\\wdsmgfw.efi";  "
set subnet-parameters   "    }   "
set subnet-parameters  "    else  "
set subnet-parameters   "           {   "
set subnet-parameters   "          # default to EFI 64 bit   "
set subnet-parameters   "         filename "boot\\x64\\wdsmgfw.efi";"
set subnet-parameters   "        }"

set subnet-parameters    "} "
