Get another SMC from donor board, same model.
Aliexpress has necesary stencils for any kind of SMC.
Just do NOT buy flux there; avoid "chinese honey" use on repair process.
I personally reball with solder paste and direct heat stencil.
Many videos available on Internet; practice on scrap boards/chips...

Don't buy flux on Aliexpress.
