Tigo optimizers are nice, and you can have just one optimizer for 2 modules. It's mostly meant for commercial bifacial modules, but it can work just fine for 2 completely separate modules. You can also use their cloud monitoring thingie to remotely track each DC optimizer's health.
Or you can use SolarEdge optimizers, they are simple and cheap (<$100 per module).
Both support automatic shutdown, so you can safely de-energize the entire system if needed. It's a problem for classic string inverters.
