IANAL and I haven't dug into the text of the law beyond your quote, but I think the key here is "for reasons of non-compliance with national performance requirements relating to product parameters referred to in Annex I covered by performance requirements included in such delegated acts." To me this is saying "the standards for performance requirements laid out in Annex I override any requirements individual members laws indicate for the same parameters, so those requirements can no longer be used to require products to meet different requirements for these parameters"
So if you are refusing a product from the market for a parameter that is not referred to in Annex I and not a "performance" requirement, then that's theoretically allowed. Depending on the rest of the text, there's a good chance that this leaves room for right-to-repair requirements, unless Annex I already has repairability requirements defined, or unless the law is written to define "performance" in a way that includes repairability.
