Yes. They just have to nominate one or more PRSA providers and facilitate access to these via payroll. They are not under any obligation to faciliate access via payroll to your existing PRSA. You could transfer your existing PRSA to their scheme but you would want to check the pros (easier admin, tax/PRSI relief at source etc.) and cons (e.g. less diversification, perhaps limited fund selection, perhaps higher charges etc.) before deciding to do so. I think that you can avail of their contributions to their PRSA but also make AVCs to your own. However if you do this then it will be out of net pay and you will have to chase down tax and PRSI relief separately. And obviously the cumulative amounts contributed (employer plus employee plus AVC I think) need to be below your age related tax relief limit to get full relief.
