Timing Chain Tensioners Replacement

I am planning on replacing the 3 timing chain tensioners on my 5 chain boxer engine. After reseaching this site I intend to employ the following guidance:

1. Index the crankshaft to TDC and secure using a 8mm or 5/16 inch locking pin
2. Lock the exhaust cam on bank 1 using the recommended cam lock tool

This assures that the IMS and the cams in bank 1 do not move when removing and replacing the tensioners. The question I have is do I need to lock the exhaust cam on bank 2 (cylinders 4,5,6) using the cam lock tool in order to replace the tensioner that is located at the top front of the engine?

Thank you,
Eric
