We would like to explain that when the Variation Gallery is enabled on the product page, the product will only display the Variation Image Gallery and not the product video and product gallery simultaneously.
It is a default functionality of the Variation Gallery option and You can post the request to our taskboard https://www.8theme.com/taskboard/ , so our dev team can read it there.
If it receives enough votes from other customers, our development team will consider adding it to one of the upcoming updates.
Such a thing may be not implemented yet due to the complexity of the implementation process, unfortunately.
We hope this information is helpful.
