As a big GDPR fanboy, one thing I would be happy for them to remove is the portability between providers requirement: it was essentially dead on arrival, is not implemented, and could be done away with.

The other EU-level regulation that needs to be either removed or completely rethought (since it will clearly not be enforced in a way that makes sense) is the cookie regulation. It was well-intentioned, badly implemented, and the GDPR addresses more of the core problems, it is time to do away with it.

But as a whole, I push back against the idea that deregulation is the primary way in which the EU can or should become competitive with the US on technology. Lack of public investment, worse ability for companies to offer equity incentives, and timid private investment are all much bigger problems than consumer protection regulations.
