The case is pending in supreme Court where as aper source private student also appeared for neet this year the time is odd right now i'll provide you exact information after a confirmation with team NTA.
Feel free to comment if you have any doubt

Is this against all the boards or is this only with nios and other state boards..as in cbse all of students attend the same paper as regular candidates..same date and time and also the same syllabus..

Also i found this on the web

Candidates who have passed 10+2 from Open School or as private candidates shall not be eligible to appear for National Eligibility Cum Entrance Test.   Furthermore, study of Biology/Biotechnology as an Additional Subject at 10+2 level also shall not be permissible. 
     The proviso in italics has been subject matter of challenge before the Honble High Court of Delhi, Honble High Court of Allahabad, Lucknow Bench and Honble High Court of Madhya Pradesh at Jabalpur. The provisions of the regulations disqualifying recognised Open School Board candidates and the candidates who have studied Biology/Biotechnology as an additional Subject has been struck down. 
              The Medical Council of India has preferred Special Leave Petitions before the Honble Supreme Court and Appeals in the Honble High Courts. Therefore, the candidatures of candidates in the NEET (UG)-2019 who have passed the qualifying examinations i.e. 10+2 from National Institute of Open Schooling or State Open Schools or as private candidates from recognised State Boards; or with Biology/Biotechnology as additional subject shall be allowed but subject to the outcome of Special Leave Petitions/Appeals filed by the Medical Council of India. 

I passed out of class 12th boards cbse as a regular candidate but got 49% in pcb.
That's why sitting for improvement exam in this year as private cbse candidate.
