How do I get an extra home Xbox switch

you don't, you'll have to wait until yours expire

I like to remind you that game sharing outside of your physical household is a violation of terms of service and can lead to account and hardware bans

I see, thank you I’ll try that now

Hi,Dany! I'm Luis, a fellow Xbox Gamer . Thanks for reaching us out here.

Ok In regards to gaining any additional switches, the only way to do so is via the Xbox Assist survey that you are offered after you receive the message that you have run out of switches. If your console shows you’ve made five home Xbox switches for the year and you need assistance, select Help when you see the message, Can’t make this your home Xbox. You may be eligible to receive an exception.

That is really the only option since support can not grant any extra swithces Dany

Game sharing outside of your physical household is a violation of terms of service and can lead to account and console bans

You'll have to wait until your limit resets on your own. Only your own console should be set as your Home. Sharing account information to use the Home setting like that violates the code of conduct and puts you and your friends at risk for being banned.
