Custom errors and disabling logging for .should()

[SebMoreno]

Is there a way to:

1. have a custom error displayed for an assertion made with .should()?
2. have a custom error be displayed without the original chai/cypress error?

I've tried several things as shown below but I haven't really been able to fully replace nor turn off an error message made with .should()

cy.visit("https://www.google.com/en");

// error message: expected <input.gNO89b> to have value Google Search
cy.get("input[type=submit]").eq(2).should("have.value", "Google Search");

// error message is the same as the original, does nothing
cy.get("input[type=submit]").eq(2).should("have.value", "Google Search", "Custom error"); 

// error message: Custom error: expected <input.gNO89b> to have value Google Search
// this displays the custom error but appends the original chai/cypress
cy.get("input[type=submit]").eq(2).should(btn => {
    expect(btn, "Custom error").to.have.value("Google Search");
});
