Remix blocked frontend route, How can I ignore some routes?

[chiga0]

I forked bolt.diy project and I replace webcontainer with other node runtime within browser. when the AI generated project run the dev server in the browser, the sdk same as webcontainer will generate a url like: localhost:3000/_i/{instanceId}/_p/{port}/index.html to preview the whole web project. But I found that the /_i/**/* route is blocked by remix backend.

So anyone can help me about this, How can I let the specified route ignored by remix server?
