Right now by default it's in 'hh:mm' I want it to be in 'hh:mm:ss' format with 1 minute interval.
Note: The image shown below is a "stackedplot" and not "plot".

In case anyone is still looking for this solution,
% Create stacked plot, set xdata as datetime values
% The XData can also be set using 'XVariable' for tables but needs to be datetime format.
sph = stackedplot(rand(50,5),'XData',datetime(2020,1,1)+minutes(linspace(0,480,50)));
% Get axis handles
ax = findobj(sph.NodeChildren, 'Type','Axes');
% Set datetime format. The first axis will be the bottom one.
xtickformat(ax(1),'HH:mm:ss')

hAx=gca;
hAx.TickLabelFormat='hh:mm:ss';
You can set the XTick values as wanted but there will not possibly be room to label more than half-hour frequency if that when you add the other text--just not enough real estate to have that much text in such close proximity.

ans =
struct with fields:
ApplicationData: [1×1 struct]
Axes: [1×1 Axes]
MaxNumAxes: 25
MaxVarIndex: 1
MessageHandle: [1×1 TextBox]
MinAxesHeight: 20
NodeChildren: [2×1 Graphics]
NodeParent: [1×1 ScribeLayer]
NumPlotsInAxes: 5
...
Plots: {[1×5 Line]}
Selected: 'off'
...
Behavior: [1×1 struct]
Well, there's an Axes handle to start probing... don't give up so quickly!!

Also, try setting the display format for the x-axis variable before plotting -- possibly the function will look at that in deciding the display format.
