[Flask] How to supress SQLALCHEMY_TRACK_MODIFICATIONS warning

[Tim Johnson]

I'm getting the following warning :
"""
warnings.warn('SQLALCHEMY_TRACK_MODIFICATIONS adds significant
overhead and will be disabled by default in the future.  Set it to
True to suppress this warning.')
"""
 
I find much chatter about this issue, but no example of
specifically how to disable the warning.

I have tried the following:
## Flask instantiation
app = Flask(__name__)
## ... other config settings
app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = True

... But the warning persists.

thanks in advance
