Yes, you should still be able to purchase new ebooks for your old portable device. However, you should know that the first generation of NOOK is no longer supported. B&N is slowly phasing out the service altogether, instead choosing to focus on their website and smartphone app. Still, as of 2022, any ebooks purchased this way will be automatically added to your NOOK Library. Any changes in this practice will be announced through B&N's social media.
