I have tried to override the form validation for telephone which added in core file vendor\magento\module-customer\view\base\ui_component\customer_form.xml as follow:

 <field name="telephone">
        <argument name="data" xsi:type="array">
            <item name="config" xsi:type="array">
                <item name="dataType" xsi:type="string">text</item>
                <item name="formElement" xsi:type="string">input</item>
                <item name="source" xsi:type="string">address</item>
                <item name="validation" xsi:type="array">
                    <item name="required-entry" xsi:type="boolean">true</item>

Tried to override this file in local module and changed the line

<item name="required-entry" xsi:type="boolean">false</item>

This remove only the mandatory (*) mark from address form for telephone number but the validation remain same.

If you removed the complete entry from base file (vendor\magento\module-customer\view\base\ui_component\customer_form.xml) then complete validation get also removed. anyone know how we can override the form config validation using local module?

At the moment making telephone optional requires quite a lot of coding. There is a discussion at github about this resulting in a module (github:/zsoerenm/magento2-optionaltelephone) being developed thats sole purpose is exactly this. However, the magento devs have already implemented a solution in core to address this. The fix in the development branch now and hopefully will soon be in master.
