Unfortunately, no. Indentation based grammars need a special lexer and a grammar which can handle the output of such a lexer. ANTLR (the parser framework used by Xtext) can't handle this.

Short answer: no

Longer answer:
Search this forum for earlier responses on this topic as people have
been positing suggestions on how to do this - not sure if there are any
successful implementations available anywhere to look at though.

But, "supported", like out of the box: no.
