In the Netherlands, there is a legal requirement to be able to show identification. Dutch citizens who are dual nationals must use their Dutch identification to comply with the law.
Identificeren bij dubbele nationaliteit
Heeft u naast de Nederlandse nationaliteit een andere nationaliteit? Dan moet u zich in Nederland identificeren met uw Nederlandse identiteitsbewijs.
Identifying yourself if you have dual nationality
If you have another nationality in addition to that of the Netherlands, you must identify yourself in the Netherlands using your Netherlands identification document.
It's not clear to me whether the law is meant to include in its scope the inspection of passports on crossing external borders, but it is certainly possible to read it as such. Government examples of situations in which authorities can demand ID do not include border controls; see, for example, https://www.rijksoverheid.nl/onderwerpen/identificatieplicht/vraag-en-antwoord/wie-mag-vragen-naar-mijn-identiteitsbewijs-en-wanneer.
So the question, as indicated in the title, is whether a Dutch national who also has another nationality can use the foreign passport to enter the Netherlands. If it makes a difference, consider that the traveler lives outside the Schengen area and the EU, and is visiting for a short time rather than immigrating.
