This depends on your skillset. The CCENT is only necessary if you don't have previous networking knowledge and have never worked with Cisco routers and switches before.
You can take the single exam track, but this has been a challenging one for many people because it assumes all the CCENT knowledge and then adds more.
You've got approx 8 months before the retirement date of the current path. So I would push for both. This current certification will still be valid until your next recertification, then you can simply move on through to the CCNP Enterprise (2 exams) instead of the current CCNP Routing and Switching (3 exams).
