Arka review for Google & YouTube

I have the 'Google and YouTube' app installed and it is linked to my GA4 analytics account. It works great. I have a problem though. I am importing conversions from GA4 into Google Ads. That works well. But I cannot seem to be able to implement 'enhanced conversions' in Google Ads. All the information on enhanced conversions says to install either GTM or Google ADS TAG. Evidently I should not have both the 'Google and You Tube' app GA4 AND GTM set up on the same site. But I don't want to uninstall the 'Google and YouTube' app. How can I implement enhanced conversions?
