error TS5023: Unknown compiler option 'enableIvy'

Question

I am trying to add IVY to my angular 7 beta project. So, I added enableIvy: true to src/tsconfig.app.json in compilerOptions section

But when I run ng build --prod --aot --output-hashing none I get below error.

error TS5023: Unknown compiler option 'enableIvy'.

Error: error TS5023: Unknown compiler option 'enableIvy'.
