That isn't sufficient. You'll also need to use an OS which provides "acceptable" hardware attestation capabilities (as defined by Google) required to verify that the copy of Chrome is legitimate (otherwise this could be spoofed). In practice that most likely means your options are limited to: Windows 11, macOS with System Integrity Protection enabled, Chrome OS, stock Android with Google services installed as system apps, iOS.
Google's first attempt at bringing attestation to the web, WEI, was shot down by hackers, but it won't be the last. Please continue to fight against this.
