Yes, you can cease paying contributions to the scheme at any time. This means your employer is no longer obliged to make pension contributions for you either. You’ll automatically be re-enrolled back into the scheme at your employer’s next re-enrolment date if you’re still an eligible jobholder (unless you’ve already opted back in). If you stopped active membership in the 12 months leading up the re-enrolment date your employer doesn’t have to re-enrol you on this occasion, but they’ll need to on the following re-enrolment date in 3 years’ time.
