Yes, after the Arrancar (Aizen) arc there is a rather short "Lost Substitute Shinigami" arc (20 or so episodes) that's manga cannon and is the ending of the original show. After the Arrancar arc they inserted filler arc but the ending leads to the same result as the canon, so it can be skipped. You can use the filler list to know what to skip, basically, Arrancar arc ends at 310, and a new one starts at 342. The show is on Hulu/Disney+ and they are numbered correctly.
