Presumptive income tax return opt out

hi friends

we have partnership firm, in FY 18-19 we opted for presumptive income and next year's onwards we are filling normal tax return and not filling under presumptive tax return

we are planning to file this year under presumptive income

our doubt can we opt for presumptive income or not we heard that can't file under presumptive for 5 years due to miss out

please clarify us, thanks for your support
