Way to force sync disk with cache=unsafe

I have a VM for source code building and running unittest.
The data in it is not critical generally. So I use "cache=unsafe" for it.

But I find that sometimes, I wish that I can force the data sync, for example
when a big project is finished to build.

A method I am using is to shutdown the VM and restart it.

Do we have any other better way to do so?
