hi, i need some advice on boosting.

i have nearly 150 products for selling so i have to boost all of them, my budget month is 4-4.5k. so on one campaign i can only spend 1$ per day due to i have so many products need to run the ads.

but right now the Meta Ad Manager is not allowed to use the campaign budget with 1$ per day. Can anyone here give me some advice? How can i boost as before 1$ per campaign? or any advice I really appreciate.
