Not all Arahants can attain Nirodha Samapatti.
– Pannavimutta Arahants who have not cultivated jhana samapatti cannot get into it. That is because one needs to proceed systematically through the first four jhana samapatti, then systematically go through the arupavacara samapatti, and finally enter Nirodha Samapatti.
See, “Nirōdha Samāpatti, Phala Samāpatti, Jhāna, and Jhāna Samāpatti”
