It's under Voice Match settings in Google Assistant settings. Unfortunately I think it's an all-or-nothing setting. Either you get Hey Google all the time or none at all. If you do disable it, you can still long press home button or the microphone icon in the widget to access Google Assistant.
Yeah just tried it myself, oh GoogleThanks for the response. The "Lock screen personal results" option is turned off for me but the phone still responds when the screen is locked.
