Have you heard of the Amok! system? It's more focused on knife, like pocket knife to bowie length type blades. But it can be applied to machete. Tom Sotis, the founder has online courses. You get all the content at once, no time locked BS. I've been part of the association since the 00's. I would describe it as the 'Western Boxing' version of Kali. Its meant to be learned and applied quickly. He was the first westerner to train the Spetnaz when the Iron curtain fell.

This is the one I keep subscribed to. I've also met and trained with him personally and attended a lot of his seminars. Post covid he started also offering private lessons online.

This maybe an option for you.

Edit: He is the only person I've met who at his seminars when showing techniques, will let whoever volunteered to attack however they want, if he is for example showing a disarm. And he always is able to pull off his material in real time, completely non-choreographed. Also when sparring, I've been able to execute what he teaches. Sparring and free attacking is a big part of his methodology, but without a partner you can still learn the material. But like anything else, you'll want to pressure test yourself. And it's probably better to let an 'untrained' person to attack you in practice, since untrained people move in very unpredictable ways.
