Hello Steveo J P,
As long as there is a video file somewhere in your Photos, then you should have a Videos option under the File Types section. The path to get there is Photos app > Albums tab at the bottom > Scroll down to the Media Types section.
If you want to create a custom album, you can do that by selecting the + button at the top left of the Albums page.

There is no setting to turn off or remove the Videos option under the File Types section. If you do in fact have video files in your Photos app, but the Videos option is missing in the File Types section, then you'd want to contact Apple to report that issue: Get Support
Cheers!
