Change marker and hide confidence bounds in Plotting multiple linear regression (fitlm)

I want to change marker for each plot and hide confidence bound

but I can not find related answer.

Where can I get a fitlm plotting properties?

Please help me :)

Thank you

X1 = R1.Research.TM_max_MFB(1,1:7) - R1.Research.P_max_MFB(1,1:7); X1 = X1*100;

Y1 = R1.Energy.bar(3,1:7); Y1 = Y1';

mdl1 = fitlm(X1,Y1);

mdl1summary = anova(mdl1,'summary');

X2 = R2.Research.TM_max_MFB(1,1:7) - R2.Research.P_max_MFB(1,1:7); X2 = X2*100;

Y2 = R2.Energy.bar(3,1:7); Y2 = Y2';

mdl2 = fitlm(X2,Y2);

mdl2summary = anova(mdl2,'summary');

X3 = R3.Research.TM_max_MFB(1,1:7) - R3.Research.P_max_MFB(1,1:7); X3 = X3*100;

Y3 = R3.Energy.bar(3,1:7); Y3 = Y3';

mdl3 = fitlm(X3,Y3);

mdl3summary = anova(mdl3,'summary');

figure(1); grid on ; hold on

plot(mdl1);

plot(mdl2);

plot(mdl3);

legend('Adjusted data','Linear ployfit ')

xlabel('MFB_Pmax - MFB_TMmax [%]')

ylabel('Exhaust Energy [%]')

load carsmall
X = [Weight,Horsepower,Acceleration];

% Fit a linear regression model by using fitlm.
mdl = fitlm(X,MPG);

% use handle for plotting
h = plot(mdl)

h = 
  3×1 Line array:

  Line    (data)
  Line    (fit)
  Line    (95% conf. bounds)

h(1).Marker = 's'   % change marker

h = 
  3×1 Line array:

  Line    (data)
  Line    (fit)
  Line    (95% conf. bounds)

delete(h(3))        % delete bounds
