Grail CF SL7 AXS tubeless tire pressure

I have the Grail CF SL 7 AXS with the standard wheelset (DT Swiss Gravel LN with 25mm and the Schwalbe G-One R tires with 40mm) and would like to convert the bike to tubeless. I ride mostly on gravel and road. What tire pressure would you recommend? I'm 79 KGs
