Wanting to replace mixed lawn with native yard -Northwest 6a

I’m so excited to finally have a yard, and to make it beneficial to the ecosystem. I have a mix of grasses, plant net says Bermuda is the main one. Would solarizing this area be the best way to get rid of the lawn? I wanted to do a chip drop but people have said Bermuda won’t die off from that. I don’t want to use chemicals if possible. I’m in southeast Idaho.
