Yes.
The basic requirement for Unicode conformance can be stated this way:
*If* a process interprets a particular Unicode character, it shall
do so in accordance with the specification of the standard.
So if a process does not interpret any Hebrew or Arabic (or Syriac
or Thaana or bidi formatting) characters, it is not interpreting any characters
with the strong right-to-left property or any specific bidi formatting
interpretation. Therefore, it can dispense with handling bidi, because
there would be context under which it would make any sense for that
process to implement it.
You can make the same argument, mutatis mutandis, for all kinds of script
support. If a process is not interpreting Indic characters, then it is
not required for it to understand the processing of virama, reordering
of vowels on rendering, etc.
