I finally got the issue fixed.If BigSur is giving this problem then Monterey will also give same problem right?
I updated my Catalina to Bigsur using software update and everything works perfectly.
The reason i think was the external ssd.
Because of which MacOS was booting very slow and the abm_firstpolldelay was not working because of it.
But After installing the BigSur on my internal M.2 Nvme ssd everything finally works like beast.
Thank you for your time elitemacx86.
