This mod's plugin comes in form of an ESL-flagged ESP file. It doesn't count towards your ESM/ESP plugin limit and can be sorted like any other ESP plugin in your load order.
LAB can only conflict with other mods that make changes to vanilla robot torso base attachments (OMOD form type). If you're using the LAB Patcher then you don't have to worry about any conflicts because it automatically makes all necessary changes to your load order.
LAB should be fully functional within the VR version of Fallout 4. I made sure that the plugin is specifically built to enable the older engine of FO4 VR to read it in its entirety.
