Unless regulators enforce (at the very least) that hardware documentation sufficient to produce open source firmware/drivers must be supplied with that hardware, no - probably not.
Drivers and firmware are the biggest hurdle outside of locked bootloaders for competition in the operating system space.
Examples; Anything Apple (MacBook, iPhone), anything Samsung, anything Google, the list goes on.
There _is_ open hardware, but it has poor performance / battery / build quality and the vast majority of users will not accept that.
IMO "the right to repair software" is essential and this duopoly is a function of explicit monopolistic practices.
Maybe LLMs can help open the "reverse engineering" Pandora's box - but we have yet to see that realised - at least for drivers / firmware
so that's basically we don't know how to make the good hardware, let's force those who know give it to us.
I'd consider that solved with LLMs (the capability is already there and will only improve). The only remaining hurdle I'd say is hardware attestation.
