You’re going to have a very difficult time finding a training guild for trials without discord on PC. People explain mechanics and call out things during fights using voice chat. Discord also necessary to put together groups in advance and ensure all people are ready for that content. Silent runs do happen but those are typically farm runs where everyone knows what they’re doing and don’t need a trial lead. Dungeons you’re more likely to find people who can type out mechanics but I’m not sure of any dungeon guild that doesn’t require discord for ranking purposes (again, so people know what achievements you have so they don’t bring someone who’s never done dread cellar into dread cellar trifecta for instance).

^ Essentially this.

It's fine, if you aren't willing/able to talk in discord for yourself, but the bare minimum is to join the raid channel at least muted to be able to hear the explanations and call-outs the raidlead is doing. Even if there were some raidleads, which are fine with writing a novel about the mechanics and the specific tasks of 12 people (I definitely wouldn't), the ability to give commands in-fight is crucial in veteran raids.

If you intend to join as healer or tank, communication is essential for coordination.

That said, for normal trials and dungeons of all sort voice chat isn't needed. So, if you aren't looking specifically for vet trials, most guilds will accept not being in voice chat if the mechanics are known.
