I need to pass null in value but I get an error, how can I extend this type?
TS2769: No overload matches this call. Overload 1 of 3, '(props: { href: string; } & { autoFocus?: boolean | undefined; classes?: Partial | undefined; dense?: boolean | undefined; disabled?: boolean | undefined; disableGutters?: boolean | undefined; divider?: boolean | undefined; selected?: boolean | undefined; sx?: SxProps<...> | undefined; } & Omit<...> & CommonProps & Omit<...>): Element', gave the following error.

Type 'null' is not assignable to type 'string | number | readonly string[] | undefined'.
<MenuItem value={null}>
Menu Item
</MenuItem>
The last sentence in the stacktracke already shows you why this error is thrown.
The value property only accepts values of type 'string | number | readonly string[] | undefined'.
So passing null is not allowed. Can you change your code to pass undefined ?
<MenuItem value={undefined}>
Menu Item
</MenuItem>
