itr filing when a demand is raised

23 August 2019  
one of my friend got a notice under non filing monitoring scheme for non filing of itr for the a.y 2016-17.
and he ignored it and the A.o has already raised the demand for 20000/- in march 2017..
can we do anything now to escape from that demand now..
please clarify..
thanks in advance....
