Not a Brave user but I have managed it at a workplace before. Far as I recall they show a wallet button at the top right near the extensions button and show crypto trading rates alongside the weather on the default new tab page. Disabling the wallet icon could be done with a right click and a left click, and the new tab page could be customized in settings to show less stuff pretty easily. Might be different now.

Happened before I even started using it, and I've been using it for a long while now. Probably time to let this one go?
> Integration of Web3 features, including cryptocurrency wallets and NFT support.
That's not a new feature, it's been in there since I started using it, and it's off by default and then easily hidden. It didn't turn up one day turned on.
> Inclusion of Brave News and sponsored images on the new tab page.
Yeah I'll give you this one. I've turned this off... I mean they're developing free to use software, so I feel bad about it. I'd probably pay for Brave at this point, but I don't want to see ads ever. At least it's easy to turn off.

I think this one is fine? I used it once when I was staying at a hotel, it was easy to use, other than that it's just hidden.
