What is the highest dodge chance I can achieve in game?

The maximum dodge you can get depends on your current standing/crouching running/walking state:

• 50% standing still
• 65% crouched still
• 75% sprinting

It's also possible to briefly get as high as 90% dodge by sprinting into a crouch but this only has a very brief overlap during which it is active.

This would require wearing the suit with Sprinter aced, Shinobi basic, Duck and Cover aced and Sneaky Bastard aced. For perks go full rogue.
