Morhps with UUID

We have an existing application using Lumen We want to replace IDs with UUIDs in several of our tables A few of these use morhps I tried replacing morphs with uuidMorphs but it was undefined Is this not supported in Lumen?

I also tried to just create the tables with the id and type fields But there are several places in the code that use functions such as morphOne and I'm not sure how to handle these
