The overall response to their interest in learning, especially from organized/official quarters like the Merchant's Guild or leaders in Orzammar's Smith Caste, would be negative and suspicious–this would be taken as a threat to their monopoly. For that reason they wouldn't have a lot of luck going through those official channels to ask for training or assistance. (And it would be reasonable of them to anticipate this and not waste their time trying.)
However, they absolutely would be able to find dwarven smiths willing to train them. They would be people who needed to be dug up specifically for being weird or egalitarian or vocal about sharing knowledge, is all. If you wanted to use a canon NPC for this, they would have no problem convincing Dagna (off in Skyhold still) to assist them, as an example. You could also make up your own NPC for it, including someone who's already in Kirkwall, and have them be as excited or as reluctant and grouchy as you want. But regardless of personality, the vibe will be that whoever is teaching them is a bit of a renegade for doing so.
Once they do know how to enchant, that in itself wouldn't necessarily be considered a serious threat, especially because there are so few rifters compared to dwarves and no way for their output of basic enchanted goods to ever match those of the dwarves and hurt them financially. It's more that among the dwarves they would encounter a lot of skepticism and wariness about their abilities and skill.
But they may run into stronger opposition if/when they begin publicly using or showing off really cool new inventions, like airships for example, that didn't go through dwarven smiths and that the Smiths and Merchant's Guild can't claim some responsibility for the success of. In that case there would likely be some attacks on their credibility. They would also experience things like people trying to steal and reproduce their work for mass (or at least more) production and public sale, or sabotage attempts to hurt their credibility, or assassination attempts to nip the problem in the bud. You'd have some control over when and how these things occurred–basically, we hope it'd be fun to RP about, not punishing, so you could use those occurrences as player plot proposals (or parts of larger player plot proposals) and create circumstances that are fun for you, rather than us telling you when and where and how it has to happen. But it would ultimately definitely happen.
