How to ensure an add-on is loaded before an integration

I have two integrations … Google Nest and Alexa Media Player that require access to Home Assistant via an external public URL. But I’m also using NGINX Proxy Manager which an add-on that doesn’t get loaded until until all integrations are initialized. NGINX Proxy Manager is what manages my access from the external public URL to Home Assistant. Google Nest and Alexa Media Player hang initializing for a long time. I’m wonder if there is a way to delay the initialization of an integration and have it triggered on the loading of the NGIX Proxy Manager. Does this make sense? Maybe I’m missing something else that is causing my problem.

Can you setup an automation to reload the Google and Alexa integrations X minutes after startup?

(Note: I’m a novice. That may not even be a thing. LOL)
