How to make lightbox prohibit left and right switching?

Question

I used lightobx to make such a photo group. Although the data-lightbox inside is set with the same name, setting the same name according to the instructions in the official document will make the photo a group and can be switched left and right, but because of the project, it cannot be set to the same name. The name of each data-lightbox is set to be different.

Is there any other way to prevent the picture from switching left and right after the lightbox is opened? thank you all.
