Has any of you had any luck modyfing .mpd query parameters, e.g. the "filter" param below:

Code:
https://ak-jos-c4assets-com.akamaized.net/CH4_43_02_900_70914001001002_001/CH4_43_02_900_70914001001002_001_J01.ism/stream.mpd?c3.ri=13505210914841619937&mpd_segment_template=time&filter=(type=="video"&&((DisplayHeight>=288)&&(DisplayHeight<=576)))||type!="video"&ts=1650237886&e=600&st=ogfRm2mgvM_yxzaYgsXEJUz0Yluvf799U7N8mG6yV1E
The above is used by Channel 4 and I'm wondering if there's a way to remove the "&filter=" part completely. Removing or modyfing it returns "400 Bad Request"...
