Cyclon 5 tampering protection bit

I have a cyclone V with an AS scheme.

I have generated an key-file (ekp) with tampering protection bit set according to AN556

Then I open it in the programmer programmer and generate a jam-file

now in the jam-file the procedure DO_KEY_SECURE is optional which means I have to enable that procedure manualy with "-e DO_KEY_SECURE" in the command, for example:
quartus_jli -c <n> keys.jam -e DO_KEY_SECURE -a <action>

is it possible to make this procedure non-optional so it will program the tampering bit by default when programming the key?
