It is not possible to set additional security on KeyChain items to ensure users presence.
See: https://developer.apple.com/documentation/security/secaccesscontrolcreatewithflags(_:_:_:_:)

e.g.
let access = SecAccessControlCreateWithFlags(
nil,
kSecAttrAccessibleWhenUnlockedThisDeviceOnly,
.userPresence,
nil
)

You hand those flags over in kSecAttrAccessControl attribute on a keychain query.

Why can this be a security risk not to hand those flags over?

TL;DR: There is especially a security risk for jailbroken devices.
