for eg:

If this is the original code,

<record id="stock_production_lot_rule" model="ir.rule">
<field name="name">stock production rule name</field>
<field name="model_id" ref="model_stock_production_lot"/>
<field name="groups" eval="[(4, ref('user_group_name..fill..'))]"/>
<field name="perm_read" eval="True"/>
<field name="perm_write" eval="False"/>
<field name="perm_create" eval="False"/>
<field name="perm_unlink" eval="False"/>
<field name="domain_force">[('....fill...)]</field>
</record>

Then first do below one,

<function name = "write" model = "ir.model.data">
<function name = "search" model = "ir.model.data">
<value eval = "[('module', '=', ' stock '), (' name ',' = ',' stock_production_lot_rule')]"/>
</function>
<value eval =" {' noupdate ': False} "/>
</function>

Then modify the rule,

<record id = "stock.stock_production_lot_rule" model = "ir.rule">
<field name = "name"> ....(updated name) </field>
<field ref = "stock.model_stock_production_lot" name = "model_id" />
<field name = "domain_force"> [(....fill..)] </field>
<field name = "groups" eval = " [(4, ref ('user_group_name..fill..'))] "/>
</record>
