Installing Office365 semi-annual updates

Hello,

According to https://support.symantec.com/en_US/article.DOC9673.html, 8.0 HF6 and later versions support Office365 updates in Patch Management solution.

My questions are:

1. Are the so called semi-annual updates supported too ? Those are equivalent of Windows 10 feature packs.

2. Our Office ProPlus package supports 18 languages such as Hungarian, Czech. Those are not available in PM settings. Does that mean the users will not receive the updates ?
For Office 2016 it was not an issue, because it was always English with the corresponding MUI pack.

Thanks,

Tomasz
