Hello. Use enum.numbering. Though because of More flexible separators in numbering patterns · Issue #905 · typst/typst · GitHub, it’s easier to use numbly.

#import "@preview/numbly:0.1.0": numbly

#set enum(numbering: numbly("(1)", "1."), full: true)

Or

#set enum(full: true, numbering: (..n) => {
  numbering(("(1)", "1.").at(n.pos().len() - 1), n.pos().last())
})
