If you do not want to steep the tea bags at the last step, you may prepare the tea in advance and use it make the latte.
To do this, we can steep the tea directly in the milk itself and use it to make the latte.
I recommend not adding water to steep the tea, because that will thin down the latte, which will be way more creamier and flavorful if you just use milk.
If you do not want to use milk, you may use almond milk or cashew milk, to make this drink vegan.
However, make sure not to use water to steep the tea for this recipe!
To steep the tea early in the process, you can boil the milk and steep the tea or microwave the milk in a large sized microwave mug for about one minute and 30 seconds and then place the tea bags and steep the tea for about 3 minutes or upto 5 minutes for stronger flavor.
Then dicard the tea bags and use this prepared milk tea instead of milk, to make the pumpkin milk tea mixture in the blender.
That way, you can directly make pumpkin tea latte in the blender (since we use milk tea instead of milk), and then heat it in stove top or microwave as per the instructions above to make the delicious pumpkin spice tea latte or chai latt, which can be served immediately!
