That depends on your default restriction.

If your default restriction allows time service (i.e. does not contain
'ignore' or 'noserve' or 'notrust') then you don't need restrict lines
for each remote time-server.

If your default restriction disallows time service (i.e. _does_ contain
'ignore' or 'noserve' or 'notrust') then you _will_ need modify the
restrictions for each remote time-server (wih a suitable restrict line)
and/or configure NTP Authentication.

Selecting the proper default restriction is discussed at

Because your default restriction is 'restrict default ignore'.
