Are dynamic selects with type inference possible?

Title. I'm trying to add select statements conditionally. I'd like the function to return a properly typed query based on what I've passed. Is that possible?

.select<SelectedFields<PgColumn, PgTable>>({
  ...(opts.groupBy && { irrigationClientId: shrink.irrigationClientId }),
  shrink: sum(shrink.amount).mapWith(Number).as('shrink'),
})

.select<SelectedFields<PgColumn, PgTable>>({
  ...(opts.groupBy && { irrigationClientId: shrink.irrigationClientId }),
  shrink: sum(shrink.amount).mapWith(Number).as('shrink'),
})

This prevents errors but isn't really what I want.
