bouncycastle FIPS license

[JSurf]

We want to use a FIPS compatible version of Keycloak within our product.

Keycloak states:
"The FIPS validated BouncyCastle library cannot be shipped with Keycloak due to license constraints and Keycloak cannot provide official support of it"
https://www.keycloak.org/server/fips

On the bouncycastle website, we could not find any license restrictions that differ between the standard bouncycastle libs and the FIPS variants.

So my current assumtion is that both variants from bouncycastle are provided under the same standard bouncycastle license as defined here: https://www.bouncycastle.org/about/license/#License

Could you clarify if my assumptions are correct or did I somehow miss a special license claim on the FIPS variant ?
