Hi
your presence is needed and you can make objection in the quash petition by appointing a lawyer on your behalf.
quash Petition most likely will not be allowed as you are not agreeable to settle and without your consenting affidavit to withdraw your allegations , it is very difficult to get a favorable order in quash petition.
The magistrate may be taking it for granted as the accuse d counsel may have informed the court about the quash petition.
It is normal that after the bail , the exemptions of appearance is allowed on personal or medical reasons.
The Presence of the accused is compulsory on all date unless there is an exemption allowed by the court.
why don't you appoint a lawyer from your side who can watch over the proceeding and if needed make objections on such permissions where accused has advantage.
