Yup! I’m using an Infinitec Pocket TV that came with a mini keyboard/mouse device. Cost me around $50 but that was awhile ago. There are lots of other devices as well.
Get them from alibaba or the other ali/Chinese websites for very cheap.
Mine works great on my 52” TV and I used it to post this. Netflix, podcasts, Pandora, games, and more all work fine.
