Oil drain screw too tight – Torx almost completely round

Hello dear community, already done several times oil change but now for the first time with the Mokka X. The screw sits incredibly tight – and the Torx is also almost complete round. I will now try to spray it over a few days with WD40 and then try again, but should it not work, then I would need a plan B. It is a round screw with 40 torx. Which auxiliary tools you could pull to the side, if it is about the Schra ube to drill out? I would be happy about any tips. Greetings
