Good news! The chocolatey 
package will be updated soon by @bcurran3 to include only the standard openHAB distribution.
Using the “Install with Chocolatey” method described on https://www.openhab.org/download/, OH2 will be installed without any pre-loaded (offline) addons and you will be able to install them as needed (using the PaperUI). See: https://www.openhab.org/docs/configuration/addons.html
