Using two POE2 Rite of Passage Golden Charm

Hello everyone!
I want to try using two unique amulets with spirits at the same time! Now I have a amulet with the spirit of the Deer and I want to get another spirit of the Monkey or Cat.

Will the bonuses of Movement Speed ​​(from the Cat and Deer) be added together and I will get +30% movement speed or will only one bonus of +15% be considered?

I want to try to make a build with the synergy of these amulets to get the maximum profit! and since it is very difficult to get them, I would not want to be upset if I receive a bonus only from one amulet! Thank you!
