Block crosspost of Google Adsense ADS but keep enable posts crosspost

Hello. The plugin works very well and each post I write on “mypersonalsite.com” site is published on “mypersonal.wordpress.com” site correctly, thanks!
Now I’d like to add some adsense advertisements on “mypersonalsite.com” site (I’d put on footer and at the end of each post, and this is possible without problem) but WordPress.com don’t want adsense ads on its platform so : Can I keep active crosspost between the sites blocking only the crosspost of adsense ads (that are published at the end of each posts? (At moment adsense is not active yet). I could publish ads only on pages that I don’t crosspost but pages are about 27 and posts are beyond 800 and I’d like to monetize them ??
Thanks in advance
J
