dyld not load library with rpath if SIP disabled

I'm working on a macOS app. Due to security requirement, I add the following line in XCode other linker flags:

-Wl,-sectcreate,__RESTRICT,__restrict,/dev/null

But after testing, we found that app crashed at launch if system integrity protection disabled. Here is the report:

System Integrity Protection: disabled

Crashed Thread:        0

Looks like dyld can't load rpath if restrict segment exist & SIP disabled. Is there a way to fix it? The framework & dylib files needs to be in the bundle to avoid other app using them, so point to /usr/lib is not an option.

Thanks.
