Not fixable warning on build

When i’m trying to build my app for web. It does succeed, but i’m having warning that i
can’t really fix by myself such as :

expo build:web
[====================] 100% (73.6 seconds)

Compiled with warnings.

asset size limit: The following asset(s) exceed the recommended size limit (244 KiB).
This can impact web performance.
  ./fonts/MaterialCommunityIcons.ttf (503 KiB)
  static/js/app.7cdde456.chunk.js (492 KiB)
  static/js/2.b451d84a.chunk.js (1.74 MiB)
  static/js/2.b451d84a.chunk.js.gz (530 KiB)

entrypoint size limit: The following entrypoint(s) combined asset size exceeds the recommended limit (244 KiB). This can impact web performance.
  app (2.22 MiB)

webpack performance recommendations: 
You can limit the size of your bundles by using import() or require.ensure to lazy load some parts of your application.

Search for the keywords to learn more about each warning.
To ignore, add // eslint-disable-next-line to the line before.

The issue is when your CI treat warnings as errors :

$ expo build:web
- Making sure project is set up correctly...

Treating warnings as errors because process.env.CI = true.
Most CI servers set it automatically.

Failed to compile.

How can i possibly fix this ?
