To delete a device from your Google account, follow these steps:
Go to the Google Account settings page by clicking on your profile picture in the top right corner of any Gmail page and then clicking "Google Account."
Click on "Security" in the left-hand menu.
Scroll down to "Your devices" and click on "Manage devices."
You will see a list of all the devices that are currently connected to your Google account.
Click on the three vertical dots next to the device you want to remove, and select "Remove."
Follow the prompts to confirm the deletion of the device.
Please note that if you remove a device from your account, you will be signed out of all Google apps on that device, and you won't be able to access them until you sign in again with your Google account.
