FPV drones are 400-500$ for DIY and 700-800$ for goggles with a Diy EFP warhead its basically a javelin type capability in every garage.
Payload-dropping attachments are basically accessories to many consumer drones.
One thing you have to take in account consumer and commercial type drones are easy to jam by design, ''federales'' world wide want to have the capability to jam these drones as a part of the requirements to enter the market. Manufacturers also offer jamming and hijacking stations for use against drones of theirs
This basically detects and gets all telemetry on DIJ drones in 2-3km radius and can locate operators(by interrogating the drone not by finding the signal) and hijack their drones

But its also possible to make drones harder to jam , by using receivers and transmitters for frequency bands less often used and low-budget frequency hoppers are at thing , primitve ones hop over 6 or so frequencies with a bit of a freeze between hoops but still quite workable. Both sides in the Ukraine war also developed patches to software and actual plug-in modules to override factory geofencing limitations and id as DJI also sells jamming and tracking systems to work specifically against its drones.
Done and counter-drone warfare in Ukraine has been evolving since 2014 and as these low tech drones are rather 'exposed' when it comes to command signals so both sides tend to launch drones and or place antennas 200-300 m from the actual operator as there is counter drone fires from artillery sometimes within minutes of detection, drones(DJI) are also flown manually first and and when returning on the last kilometer or so as return to home signal and coordinates can be intercepted again as said DIJ is consumer-grade drone, vulnerability is built in by design
