I have a set that I use specifically on HP notebooks when this happens. I can't find the set on amazon, but this is somewhat similar to what I have: https://www.amazon.com/Extractor-Stripped-HassleFree-Hardness-63-65hrc/dp/B07GZ17QD9/ref=sr_1_5?crid=2TEI7KBVKGILY&keywords=screw+remover&qid=1647432926&sprefix=screw+remover%2Caps%2C96&sr=8-5
maybe something like this https://www.amazon.com/Extractor-Stripped-HassleFree-Hardness-63-65hrc/dp/B07GZ17QD9 or a dremel and carefuly cut a slot for a flat head screw driver
