As of today you can disable flow via PnP Powershell script found here: https://www.cloudappie.nl/disabling-flow-powerapps-buttons/
BUT there is no way to disable PowerApps. :(
So only way I have found to do this is to go to O365 Admin center - Users - click on user and go to product licenses - view details in resulting window, then EXPAND Office 365 Enterprise License (click next to arrow) and it will show all the licenses. You have to turn off Flow and PowerApps for each user. Not an optimal solution but it does at least work.
