How to mask with a pattern but commit without the pattern

[angelod1as]

I'm using react-imask: 6.4.3.

I have the following component:

    <MaskedInput
      maskOptions={{
        mask: "**************000",
        prepare: (str: string) => str.toUpperCase(),
        eager: true,
        validate: (str: string) => !regex.vin.INPUT_VIN.test(str),
      }}
      defaultValue={value}
      onAccept={onChangeValue}
    >
      Label
    </MaskedInput>

I need the displayed values to have a space between some character, so I modified the mask to:

mask: "**** **** **** **000",

The issue (for me, as I understand that's expected) is that the value commited to onAccept is with the spaces. I need it to only show the spaces, but commit without it.

I came to this solution but I think there might be a better way.

    <MaskedInput
      maskOptions={{
        mask: "**** **** **** **000",
        prepare: (str: string) => str.toUpperCase(),
        eager: true,
        validate: (str: string) => {
          return !regex.vin.INPUT_VIN.test(str.replaceAll(" ", "")) // Here
        },
      }}
      defaultValue={value}
      onAccept={(value) => {
        return onChangeValue(value.replaceAll(" ", "")) // And here
      }}
    >
      Label
    </MaskedInput>

Is there a way to show the input with a pattern but commit with a different pattern?
