Upgrade internet speed + avoid contact with technician during COVID-19 outbreak

Because I am working at home and kids are taking lessons online, I would like to upgrade my internet from Internet 24 to Internet Internet 45. When I try to make the purchase, it says a technician has to come over to make the change. Is this something that can completely be done outside, seeing as I already have Internet 24? Or does the technician have to come inside the house?
