I managed to get a DT Swiss XR 331 working with 2 layers of orange seal tape yesterday. it didn't make a noise mounting but held pressure overnight with some sealant.
it was my 2nd go. first time I put tiny holes in the tape at the spoke holes by pressing the tape too firmly into the well. could hear the air coming out. 2nd time I didn't press it into the well.
I have the same rim in a factory wheel and it came with a metallic looking tape with "tubeless ready" printed on it. that one did make a loud pop and mounted very easily. you can buy DT brand tape. not sure who makes it.
