Dear Sardar Miyan
Salam
Its nice to hear you in this forum. At this age you are still actively in search of truth, thats quite encouraging.
In fact we do lot of things which are not mentioned in the Quran. Lots of practises have been incorporated in our religious practises over the centuries. The prctices which does not conflict with the core teachings of the Quran then there should not be any problem, I think. The salat of two Eid are such practises. Those are not compulsory. I hope, we would not be questioned if we abandon it due to our difficulties. But those are good practises to follow.
Allah knows best.
Regards.
