Turn off virual pin in DSPBA

Hi all,

GPIO blocks in a DSPBA Simulink model generate in the modelname_dut.tcl file

source ./rtl/fixed/dut/fixed_dut.add.tcl
set_instance_assignment -name VIRTUAL_PIN ON -to In1
set_instance_assignment -name VIRTUAL_PIN ON -to Out1
set_instance_assignment -name VIRTUAL_PIN ON -to Out2
source "./rtl/fixed/dut/fixed_dut_fpc.add.tcl"

How can I turn VIRTUAL_PIN OFF. I want to do my own assignments in a different TCL script something like the following

source ./rtl/fixed/dut/fixed_dut.add.tcl
mytclpinassignment.tcl
source "./rtl/fixed/dut/fixed_dut_fpc.add.tcl"
