instead of using 0 and 1 to choose the device, could we try using the name? https://github.com/analogdevicesinc/hdl/blob/dev_adaq4224_main/projects/ad4630_fmc/common/ad4x3x_bd.tcl#L95-L102

something like this:

switch $S_FPGA_CARRIER {
  ZCU102 {  ...  }
  K26I {  ...  }
  default { ... }
}

We could use a variable like "DEVICE"

make DEVICE=AD4630 etc
