Drizzle Schema Boolean

Hi everyone, I'm trying to create a schema in Drizzle but my SQL knowledge is pretty limited. I want to have a boolean like isProtected and if this is true then store some other information in other columns. I dont know how to handle a situation like this.

  isProtected: boolean('is_protected').default(false).notNull(),
  contentType: mysqlEnum('content_type', [
    'application/vnd.apple.mpegurl',
    'text/xml',
  ]),
  contentUrl: text('content_url'),

  isProtected: boolean('is_protected').default(false).notNull(),
  contentType: mysqlEnum('content_type', [
    'application/vnd.apple.mpegurl',
    'text/xml',
  ]),
  contentUrl: text('content_url'),

I want to have these contentType and contentUrl columns to contain value only when isProtected is true. Basically, Is there a way to make sure that when I set to isProtected true Typescript will force me to add other related columns ?
