Did middle eastern immigrants to latin America change their surnames?

And if so, was this a personal choice or more do to societal pressure? Or a compramise for convienience? (im asian american, so I use an english name in public but my parents call me by my birth name). Sorry if this seems off topic, but I noticed that salma hayek's lebanese dad seems to have a Spanish surname (dominguez), while she herself keeps her Arabic surname, and was wondering if this was a common phenomenon in mexico/other latam countries.

Edit: here is salma hayek paternal genealogy. https://ethnicelebs.com/salma-hayek. It appears her paternal great grandfather went by nayib hid, then became Narciso dominguez marun. It appears his daughter adela (salma grandmother) did not inherit her mother's surname at all. Curious as to why.
