ILR for child born outside of the UK

I am completing 5th anniversary of tier1 entrepreneur visa on 8th December 2019 and my wife also completing 5 years tier 1 entrepreneur dependent visa on same day. We have two sons who are 12 years and 9 years old. They were come to this country on my tier 1 child dependent visa on 2015 and back to the country on 2017. Again they came back to the UK on my tier 1 child dependent visa on may2019 and sep 2019(arrival difference date). Can our sons apply ILR with our ILR application on same time (8th December 2019)?

Hi GURUS
I am completing 5th anniversary of tier1 entrepreneur visa on 8th December 2019 and my wife also completing 5 years tier 1 entrepreneur dependent visa on same day. We have two sons who are 12 years and 9 years old. They were come to this country on my tier 1 child dependent visa on 2015 and back to the country on 2017. Again they came back to the UK on my tier 1 dependent visa on may2019 and sep 2019(arrival difference date). Can our sons apply ILR with our ILR application on same time (8th December 2019) without completing 5 years ? which application form SET(O) or SET(F)?

Please do not post ilr questions in the tier 1 Entrepreneur sub forum!!
