Is it possible for existing Internet customers who were on ACP to convert to Internet Essentials Plus?

I am an existing Xfinity Internet customer. I was getting the ACP discount for a while, until the ACP program was canceled. So now my Internet costs a lot more than it used to. When the ACP program was canceled, I got an email from the government saying I could use Lifeline instead of the ACP program. However, my research today says that Xfinity does not participate in Lifeline. I looked up online, and it seems that Internet Essentials (50 mbps, for 9.95) and Internet Essentials Plus (100 mbps, for 29.95) are the only low-income options that Xfinity offers. I have seen various conflicting information about this. Some things I read say that only new customers who have never had Xfinity Internet can get these plans. Other sites say other things that are unclear. So I don't know what the actual answer is.

Anyway the point is, I am an existing Xfinity Internet customer who qualified for ACP and was getting that until the ACP program was canceled. Is it possible to convert my existing Xfinity Internet to the Internet Essentials Plus program for 29.95/month? And if so what is the process for doing that?

And if it is possible to get on the IE Plus program, does that require a contract? (I am not on a contract right now)

Also, I have my own modem. So equipment is not needed.
