so, i went web surfing for an evade in campaign, and i found one lead:
“Yes it is but its dangerous to get it.its in each level in hidden places since evade is a special equipment in pillar of autumn there’s a cliff but i warn you there’s no sign.so anyways you gonna have to grenade jump it (ask a friend to throw a second grenade)then when your on top you should see something square with a purple circle,there’s no sign but pick it up quickly because your gonna be out of bounds.this worked for me and my friend oh and in co-op how many players r there will be how many evades r there (3 players = 3 evades)”

im working alone, but you guys should really try to see if it is true. Im going to search in a few minutes.
