CC1312R: Setting RATGPO1 as Rx sync signal with Syscfg

I need to output the RATGPO1 signal configured as Sync Rx signal detection.

I read in this forum that I have to place first an override "0x008F88B3"  used in CMD_RADIO_SETUP.

I am using Easylink with SysConfig tool, is it possible to add this override value using SysConf? (I did not find the way to do so in the manual).

Thank you in advance,
