What are you referring to as the daily health tracker? Do you mean the panel with the Daily Activity heart? Open the health app. While you are on the home page, tap the dot menu and select "edit home". Then tap the minus sign in the upper right of any tile you do not want to see. You cannot get rid of the "hints".
Or, are you referring the the Samsung health app itself? The health tracker (unless you installed a third party app), is part of Samsung Health. You can uninstall the Samsung Health app. It's in your apps list.
Why do you want to uninstall it - is it sending you notifications you don't want? You can turn off the notifications.
