'I am trying to set a new value to the singleton method that has already being defined in ruby but I could not find a proper method to do so

define_singleton_method(:node_name){ "NODE0003" }
=> :node_name

node_name
=> "NODE0003"

I tried to change this value using set_to method but gives the error

node_name.set_to("Node")
Traceback (most recent call last):
        5: from /Users/kr018/.rbenv/versions/2.7.2/bin/irb:23:in `<main>'
        4: from /Users/kr018/.rbenv/versions/2.7.2/bin/irb:23:in `load'

        1: from (irb):55:in `rescue in irb_binding'
NoMethodError (undefined method `set_to' for "NODE0003":String)

Could someone help on this ?
