Poor page speed score after custom code integration

Website giving very poor page speed performance after I added third party integration code like

Weglot,
Finsweet script for cookies,
Google tag manager script,
adroll integration,
Hotjar tracking code,
Linkedin ad script

Is there any way to improve website performance with all the above tracking codes?

Website URL is:

Read-only link:
https://preview.webflow.com/preview/metamap?utm_medium=preview_link&utm_source=designer&utm_content=metamap&preview=e92e353b3de0e0c6e3375452b5f51fef&workflow=preview

So you mean, there is noting we can do with third party codes?
