In a very limited way. Some countries are moving some government systems off US suppliers, but its very limited.

Somethings are going the other way. For example (there was a post about this on HN a few days ago) the new EU ID/age verification app depends on Google or Apple attested phones.

There is no real effort to push the private sector off American systems. Your government might technically function but its going to be crippled if your private sector has ground to a standstill.
