Huawei Y5 2 Encryption

Hello. I renctly bought a Huawei Y5 2 with Android 5.1, I want to encrypt my phone but as I can see in the settings/security menu I cannot choose that option, and I just read that Huawei does not let you encrypt it. So i was wondering, is there any way to use a 3rd party app or something like that to encrypt my phone? Full disk encryption is a must.

Thanks
