Disable single radio choice from Grouped Radio Action Buttons

I have a below shiny code, I am trying to disable single radio button choice from grouped radio buttons. I can disable complete radio button using shinyjs::disable() function. But, having trouble disabling single choice.

library(shiny)
library(shinyjs)
library(shinyWidgets)
if (interactive()) {

  ui <- fluidPage(
    useShinyjs(),
    radioGroupButtons(inputId = "somevalue", choices = c("A", "B", "C")),
    verbatimTextOutput("value")
  )
  server <- function(input, output) {
    output$value <- renderText({ input$somevalue })

    shinyjs::disable(id="somevalue")

  }
  shinyApp(ui, server)
}
