(request) dell latitude 7490 unlock bios ?

hi ,

here is my problem:

i have a dell latitude 7490 laptop and i thought it get the thunderbolt but i realized that it is an option and too late for get it…

i am pretty sure it is not an hardware modification, i think it is just a bios modification because if you have thunderbolt you can change settings in bios (and i can’t change or see them)
do you know if it is possible to add option in the bios?
here is the link to the bios
