If you turn off chrome sync, they won’t get most of it. And with the removal of third-party cookies, Google’s other primary method of appending to https://myhistory.google.com (showing you the websites where Google has received a logged-in cross-origin ad request) will also be gone.
You don't have to turn off sync. Chrome supports end-to-end encryption for sync data. Set a sync password that is different than your Google account password to enable it. This will disable history sync but everything else will still be synced and unreadable by Google.
