File libMonoPosixHelper.dll has failed the DBCheck check. - Linker options for UWP application?

I'm trying to submit my app to the Microsoft store, but I'm encountering this error:

Error Found: The binary analyzer test detected the following errors:

 File libMonoPosixHelper.dll has failed the DBCheck check.

Impact if not fixed: If the app doesn’t use the available Windows protections, it can increase the vulnerability of the customer's computer to malware.
How to fix: Apply the required linker options - SAFESEH, DYNAMICBASE, NXCOMPAT, and APPCONTAINER - when you link the app. See links below for more information:

According to the information i have read it's not possible to change linker options for a C# UWP application. If so how i am supposed to remedy this problem? As far as i know the libMonoPosixHelper.dll comes from Mono.Posix.NETStandard, (which is a dependency from another package I'm using: PeachPie.Library,). And Mono.Posix.NETStandard is a package developed by Xamarin and Microsoft and provides "Posix/Unix features". Any help is appreciated.
