De Boer is available after his dismissal by Palace earlier this season.
"I want to think about it," De Boer told Ziggo Sport. "I am a doer, I like to stand on the field and prefer to work with a group of players every day, but as a national coach this is not the case.
"So I will have to take that under consideration with me."
De Boer, the former Ajax coach, did also admit no offer from KNVB had been fielded.
