Vostro 3470, wireless card swap

I recently purchased a Dell Vostro 3470. It was only after I received it and got it all set up that I realized it as not 5g compatible. Can I swap out the wireless card (or some other hardware) so that I can connect to 5g? Any instructional videos or guide as well would be much appreciated. Also, anyone notice it is nearly impossible to find just an email address where you can email the company directly? Anyway, thanks in advance for any/all feedback as I try to resolve this issue.
