Can My dads Wife Prevent Me From Attending my Dads Funeral?

His wife is not my mom just some lady he got married too.
I’m my dad’s Biological Son he Did not have any Biological Children with his Wife.
My dad died I got a call last night To inform me of his Death 💀 and I want to go to his Funeral and I just want to know if his wife can legally Stop me from Attending his Funeral.
