I created just an example dashboard with two tabs using tabPanel. You can use the following code:

library(shiny)
library(shinythemes)
library(shinydashboard)

shinyApp(
  ui = navbarPage("Dashboard", theme = shinytheme("flatly"),
                  tabPanel("Tab1",
                           sidebarLayout(
                             sidebarPanel(
                               fileInput("df",
                                         label="Upload FCM Data"
                               ),
                               fileInput("dl",
                                         label="Upload Device AX Data"
                               ),
                               
                               uiOutput('choose_TEC'),
                               uiOutput('choose_OP'),
                               uiOutput('choose_APL'),
                               uiOutput('choose_PRD'),
                               uiOutput('choose_DEV'),
                               uiOutput('choose_NACol')
                             ),
                             mainPanel(
                               h2("text tab 1")
                             )
                           )
                  ),
                  tabPanel("Tab 2",
                           sidebarLayout(
                             sidebarPanel(
                               sliderInput("slider1", label = h3("Slider"), min = 0, 
                                           max = 100, value = 50)
                             ),
                             mainPanel(
                               h2("text tab2")
                             )
                           )
                  )
  ),
  server = function(input, output) { }
)

Output looks like this:
