Evisa for Dual Nationality

Hello All,
I'm Egyptian with a settled status on my Egyptian nationality, I received my 2nd nationality on 2022.
My Egyptian passport is added to my evisa account, I'm trying to update my details to add my Hungarian passport as well cuz of Brexit and limitation to Europeans movement in and out of the UK.

It refuses and says that you are adding a Hungarian passport which isn't your nationality.

1. can I add my Hungarian passport on the same account which was created 2018 on my UKVI account? The way please
Thank you in advance

I think you can't do it online, you need to contact EU Resolution Centre and probably you will need to post your documents to them, so they can add them manually

Thanks for your reply, I will contact them.
